Very interesting points, i have a (noob) question about point n.2. Could the question about GDPR can be circumvented by having a anonymous profile ? Could this be applied to other platforms?

Meta can and will pay for it. They have enough funds to run their own instance.

I am reposting my answer from another thread : Nothing good will come from meta ( or any other Gafa Microsoft included), ever. They will alway look for a way to corrupt any social media to their favor in order try to dominate the Web. At this point of the internet history anyone giving a speck of trust to them is dream walking into a disaster waiting to happen. There are already trying to bring Insta and activityPub service lol , and they didn’t haven’t started yet.
