I'm struggling to think of a reason that Meta is implementing ActivityPub protocol in Threads. There are a couple of possible reasons:
- access to an instant user base
- potential to influence a worrying rival
What I can't figure out is how they intend to make money while allowing external instances access to the content? After all, any client could be used to strip out ads. It just doesn't feel like it benefits Meta.
It leaves me a bit worried that they intend to divert the protocol in some way.
