I think their strategy is not gonna work. Meta is universally hated by everyone using the Fediverde now. The majority of Mastodon / Lemmy users are here looking for alternatives.
Also, I dont think Facebook and Instagram users are looking for a Twitter alternative.
Also, Meta is good buying stuff (Instagram, WhatsApp) but they have a history of trying new apps that are never successful.
I predict Meta Threads will close in a couple of months.
I think it is very well explained. You don’t need to go to other instance to follow them.
They are just merging with another community for convenience.
I don’t get why are you so upset. It’s not a big deal.
Also, you can create your own community in any instance you want.
