It baffles me that so many don't see it for what it is.
Meta contacts their competitor, and says that they want to build a competing product, and want us as competitor to help them with that. How can you possibly fall for that. Meta can already use activitypub for whatever they are building without any need to contact anyone from the Fediverse. The only possible reason they contact instance admins is because Meta wants to dictate the terms on how to Fediverse operates.
