I'm becoming more suspicious of Facebook's project to integrate a new service into the fediverse.
It makes absolutely no sense.
An open 'social network protocol' and its implementaions are a threat to multi-billion companies like Facebook who absolutely need to retain tight control over their user base to extract profits.
Once plugged in the danger of their user base 'escaping' through the new connection is large.
But I still can't quite pin down why they are doing it.
