Meta can rage farm Mastodon without controlling it
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.
The moment I start seeing Meta content here is the moment I leave. People are being very, VERY naive in thinking that the Fediverse is immune to corporate interest. Judging by the Mastodon response, we are already seeing that it's not.
In email world, gmail became so successful that now its a problem when they decide to blacklist any other email domains that Alphabet don't like. We should never allow profit driven entities get their foot in the door. We should develop a strong immune system against such profit seeking groups/companies etc. We should remain open to people, non-profits, universities and the likes only.
I think the immune system is federation itself. Everything is in the open, users have the control, how do you develop a competitive advantage in that context? I think it's the end of "winner takes all".
