Well, ultimately mastodon/lemmy are hobbyist projects. They would naturally count as “provided as is, with no guarantees”.

I don’t know about Lemmy, but Mastodon the software project is most certainly not a hobbyist project, blowing it off as one is just tone deaf. It’s a real non-profit company with actual developers on an actual payroll. mastodon.social and .online are real expenses on the balance sheet of that non-profit. pawoo.net was started by pixiv, a for-profit company, but changed ownership several times and is now owned by Sujitech LLC (along with mstdn.jp and mastodon.cloud). The owner of misskey.io is also in the process of forming a company.

Yes, they are “provided as is, with no guarantees” but the people who run them are completely and sincerely invested in their sustainability as more than just hobby projects.

All big fediverse instances are funded by users.

This isn’t true for a lot of them if you actually take a look. Consider the top 10 instances according to https://fediverse.observer/list

• mstdn.jp, pawoo.net, mastodon.cloud are run out of pocket (by the same owner (!!!)).
• misskey.io is partially funded by ads., registrations from non-Japanese IPs were also closed shortly after the Musk takeover.
• Funding for mastodon.social and mastodon.online is co-mingled with the funding for Mastodon the software project
• baraag.net barely has the funds to secure enough capacity for the number of users it serves (registrations have been closed for the past year)
• The admin of mstdn.social was apparently short on rent this month? (!!!)
• daystorm and pravda don’t count because their numbers are spoofed
• mastodon.world and mas.to can count themselves as lucky enough to be truly user-funded and (seemingly?) sustainable.

OP may not be good at phrasing things, but their concerns are completely legitimate. Almost ALL of the biggest instances are unsustainable on their own or have had to make compromises in order to stay online.

How have you determined these communities are no longer a legal concern?

The lack of an ability to prevent someone from doing something to you, without compromises on your part, is not the same thing as being okay with it being done to you.

3rd party services can access the posts, because the authors marked them as publicly accessible.

Those same 3rd party services can also index the posts in a search engine, but this is only because there is no feasible technological barrier to prevent them from doing so. If such an imaginary technology did exist, it would have been deployed already.

In the mean time, we can only count on a social solution, which is to merely signal our objections to search engine indexing, in the hope that maybe a law could be drafted that uses that as precedent to make indexing without consent illegal.

Here’s a question for you. Do you think it’s okay for Google or whoever to install invisible cameras everywhere in public spaces, that were explicitly for the purpose of collecting data to develop a facial recognition model to search people without their consent? Public space is public space …

Feeds/timelines are first-class citizens in the AT protocol and are decoupled from account hosting.

On Mastodon, your timelines are computed by the same server that hosts your data. Consequently, signing up to a server to have an account on the fediverse is the same thing as joining a community. You follow the servers rules and share the same local timeline as everyone else on that server.

On Bluesky, feeds are arbitrary, fungible and provided by any server, and it can be computed/curated/moderated however they like. So communities are “built” around feeds rather than around account hosting providers.

The AT protocol also has “real” account portability (though I have not seen this demonstrated in practice https://atproto.com/guides/overview#account-portability). On Mastodon, account “portability” is a delicate dance that requires the cooperation of both the origin and destination server.

Mastodon has something that Bluesky currently doesn’t: real federation. The Bluesky server that everyone signs up to doesn’t federate with anyone else, since the whole protocol is still a work-in-progress.

You’re conflating tagging a post as public so that it is publicly accessible as being the same thing as consenting to being indexed in a search engine.

Google and Bing’s crawlers can find and index Unlisted posts just as easily as any other.

Just because there are 3rd-party search engines that don’t respect people’s privacy, doesn’t mean that a 1st party search engine should follow their example.

Spam has consistently been the death of the open internet, even the big tech silos struggle with spam (Instagram for example – despite having incredibly invasive techniques for identifying “genuine” users – is STILL inundated with spam commenters). I think instances on the fediverse should reconsider their open registration policy, either totally close registrations when you reach an agreed upon critical mass of users, or adopt some form of invitation or application system for new users. I believe Mastodon supports both in the software.

no receipts?

Matrix tackled this UX issue in the bud relatively early with https://matrix.to/. It still isn’t ideal, but much better than expecting users to install browser extensions or OS-specific hacks to properly handle ActivityPub links.

I was going to join calckey.social/firefish.social but I’m a little hesitant now because mastodon.art defederated with it, and I follow multiple accounts from that instance. The drama that always surrounds defederation is a fundamental design flaw in the Fediverse

mastodon.art is unfortunately run by a harebrained power mod. Their predecessor was much much better and more thoughtful in their use of moderation powers.

a twitter-like platform needs a big central algorithm that can associate posts with certain topics and interests to be able to serve up an interesting feed

I grew up on Tumblr and it thrived for the longest time with a chronological timeline.

most people are just kind of shouting into the void and that endless storm of posts has to be filtered and organized somehow

Yes, it was done through tagging. Notably, tags in Tumblr didn’t have to be inline.

Tagging died on Twitter because the inscrutable blackbox of the algorithm made people unsure if tags actually improved the visibility of their posts or not, there’s some folk-wisdom that suggests excessive tagging leads to deboosting of your profile, since it could have been considered spammy. Also, there’s only so many characters in a Twitter post and sometimes there’s just not enough left for relevant tags.

1. This isn’t just a Mastodon problem, all fediverse softwares struggle to keep an accurate tally of faves/likes/whatevers on posts from remote instances

2. It doesn’t look like this anymore on mastodon.social

3. Search isn’t free so it’s up to the admins to decide how good/powerful they want their search bar to be.

4. It shows all followees/followers of a user if said user is local, but if the user is remote, it will only show local followees/followers of that user because knowing what remote accounts follow what remote users also isn’t free.

The entire point of Twitter is for celebrities, brands and governments to have a single place to be able to send out a public message and for that message to be seen by everyone

Nothing about Mastodon or the fediverse prevents this. In fact government institutions are already using the fediverse this way: https://social.network.europa.eu/@EU_Commission https://social.overheid.nl/@belastingdienst There’s some companies who run their own instances also, and no shortage of individuals running single-user instances as a subdomain of the same website they use for their professional brand.

Decentralized =/= Federated. In a federated model, data is still siloed in 24/7 servers that are controlled by people or institutions.

PaperWM really should be its own DE. It’s so good, almost perfect, but held back by its nature of merely being a GNOME extension.

It depends on the software. Some proxy all content from remote servers so you only connect to your home server (Mastodon). Others don’t, instead they make clients load remote content themselves (Lemmy). If you use browser client you can see all the connections being made.
