I always find these arguments are almost in bad faith. Sure there are always alternatives, but that’s like saying the alternative to driving to work is walking. It works, but only so far as it is practical. I am so glad I found Lemmy and fortunately the community has been forced here by Reddit, but how many posts were on this platform 2 days ago, how many will be here in a week? I am hopeful this will last, but platforms are only as powerful as their users, and the general public tends to congregate in the largest, easiest to use location.
For me at least, I found here the same kind of content I used Reddit for, so as long as these stay around I have good reason to do so.
I also like the federation “movement”, (imo) it feels more cozy and enhances the sense of a community.
i mean yeah you can find an alternative of a certain service, the problem is the little or few content are in certain services or a few little community engaging.
Be the change. If few people actively try to build an alternative the network effect will do the rest.
