First, scammers used to set up a Google docs with a survey inside Google for users to fill out. Google cracked down on those.

Then, scammers started adding external links to Google docs,so people would see the doc was on Google and trust to click on the link. Google cracked down on those.

Now, scammers are exporting the Google docs webpage and hosting it somewhere else, so it still looks like Google and makes people trust it, but outside of Google’s control. Google is now cracking down on those by replacing every link with a redirect through Google,.so olevwn if the HTML export isnhosted somewhere else, Google gets to scan and block malicious links.

Personally I’m against it (tampering with user data) and I think it’s only going to stop the scammers who forget to replace the exported links, which seem like an easy thing to do.
