I red tha article and I think there is a problem in who it was managed at the time, if Google or Meta wants to join they should to us not us to them so if they break federation we should not care and continue implement our stuff, if something usable comes out of them joining we could use that but we are not their slaves, they are going to play in our home so we establish the rules.
Plus I think that if we don't become meta's costumer support and I don't think we will, we are not that dumb, meta joining the fediverse would only benefit us because we could see all the posts from Meta while being on a private add free server, people wouldn't have to choose between Instagram where all their friends are mad pixelfed ecc.
What do you guys think? Open to talk.
