Well look, I don't have enough insight into the design or backend for Lemmy or mastodon, but Facebook has heavily invested into their network, and likely aims to grow.

How could they do that? All of this seems blockable on the client end (meaning I'm not good/shitty enough to work at Facebook) but imagine:

an algorithm takes a selection of high ranking fb posts and cross-posts to Lemmy, far faster and more frequently than regular users. Oh, you'll need to login to read.
threads could wholesale repost other users and their comments, but behind a threads login wall

Basically do some scummy behavior using our public statements, questions and comments, all to get more attention devoted to what's happening on their site (and its associated ads).

So what? The Lemmy meme communities make posts way faster and more frequently than any other communities. Did I solve that by demanding my instance admin not federate with those instances or communities? No, I just unsubscribed from them.

And if Threads send encrypted / locked posts to Lemmy that cant be read on Lemmy clients then you just defederate from them then.

So? How does Threads forcing their users to sign in make your experience using Lemmy any worse?

No need for an antagonistic tone here, just conversing with you.

I think this would be a problem now for people like me who enjoy browsing all, where the feed would get overwhelmed by facebook-sourced content.

And I don't like meta as a company, so it shouldn't be a surprise that many people do not want to provide any data whatsoever to them via threads etc.

Except that you're posting publicly and there is absolutely nothing that prevents Meta from scraping all of your lemmy activity as it is.

Precisely my 2nd point.

I thought your second point was ~ 'Lemmy instances shouldn't federate with meta because you don't want them getting your data', not, 'it doesn't matter whether or not we federate because they can scrape that data off Lemmy anyways'.
