Meta can introduce their signature rage farming to the Fediverse. They don't need to control Mastodon. All they have to do is introduce it in their app. Show every Threads user algorithmically filtered content from the Fediverse precisely tailored for maximum rage. When the rage inducing content came from Mastodon, the enraged Thread users will flood that Mastodon threads with the familiar rage-filled Facebook comment section vomit. This in turn will enrage Mastodon users, driving them to engage, at least in the short to mid term. All the while Meta sells ads in-between posts. And that's how they rage farm the Fediverse without EEE-ing the technology. Meta can effectively EEE the userbase. The last E is something Meta may not intend but would likely happen. It consists of a subset of the Fediverse users leaving the network or segregating themselves in a small vomit-free bubble.
Mastodon is a bubble. You have primarily highly educated, tech-literate nerds on that platform.
Obviously people are more civil and polite there, than some raging uneducated losers and trolls on facebook.
As the fediverse grows, the userbase will obviously lose this current isolated tech-wizard school vibe, and feel more like going into a random pub in a big city. Regardless if Meta joins the fediverse or not.
Does it? Facebook can determine things like political leanings of people, as well as the likelyhood of particular content to trigger rage response. The result looks different for different people. Everyone's feed is different and tailored for inducing response from them.
When I used Facebook a few years ago, my feed was mostly memes, ads and personal posts from friends and family.
Maybe I never got the ragebait political stuff, because everyone in my friend circle wasn't keen on being the sad guy that publicly yells at clouds on facebook.
Popular hashtags on Twitter and to some extend even on Mastodon, just makes you feel bad for the mental health of these perma-raging users tho.
Political spaces in general on every social platform are just magnets for misery.
