Facebook has been able to get around ad blockers for years. Google’s probably going to be able to do the same.

More specifically it comes from a myriad of subdomains that they rotate all the time.

It was a very popular 3rd party Twitter client that Twitter actually bought way back when.

They don’t need personal information. If the owner of a server doesn’t like what you post , they can ban the account. They run the whole machine so if they really wanted to they could block your IP from even connecting in the first place!

Decentralization doesn’t mean you’re free to post whatever you want. It’s still someone else’s computer, and they make the rules. Federation doesn’t change that. Sure it’s harder to suppress information, but a few admins could easily coordinate against you if they so wanted.

Being decentralized doesn’t make you immune to censorship.

Google+ also infected other Google products and basically forced itself onto folks who didn’t even want it, making it tainted from the start. It’s not like Threads is being forced onto WhatsApp users or anything. The only thing that’s possibly going to be an issue is once they start adding advertising, but I doubt that’ll matter much.
