But that’s the risk taken when you create a protocol (ActivityPub) that anyone can tap into. You can’t create something that is open to everyone and then pitch a fit when entity you don’t like or agree decides to take advantage of it. Regardless of how big Threads get, it can’t supecede the ActivityPub protocol. If they decided to defederate down the road in attempts to extinguish the Fediverse, it won’t work, those users will still remain and Threads will go on it’s merry way. Meta can’t kill a W3C protocol.
The only posts bots should be making is mega threads for events. Content posted should be organic from the user to drive discussion and not what some bot wants to repost from Reddit/hn/etc.
I’ve already blocked several bots to improve my experience, since my feed was being overrun by bots posting to various communities.
