People are fearful then meta will retract it/ defederate and take the majority of content with it (EEE). This would effectively kill the fediverse.
I don’t see how that could possibly happen. It’s not like they can buy the Fediverse. Seems to me far more likely that the Fediverse will be gain interest from people wishing to follow/interact with Meta users without being beholden to Meta and if/when Meta decouples from it again the Fediverse will be larger than before. Sure, some may come and go, but others will find interests outside of Meta.
Like everyone is pointing out, they already will be the largest instance. They are not going to gain that much by trying to trying to absorb the rest of people who are likely in the Fediverse from dissatisfaction with Big Tech and wanting to break free from their algorithms and restrictions.
I am extremely skeptical of 2 and 3, because it means people who already decided to drop mainstream social media platforms will go back on their decision, and it suggests that people want instances to be more like Meta, rather than for it to function in a user driven way that provides things that Meta will never be willing to offer.
If people can be tempted off of the Fediverse so easily, the problem is not Meta. Keep in mind that right now people are already choosing not to engage with Facebook. I’m not naive to assume that they won’t have appeal and influence and dirty tricks. but seems to me like such a complete lack of faith in the Fediverse to assume that if Meta merely exists alongside the ecosystem, it’s inevitable that everyone will jump ship. That sounds like what they wanted was a Big Tech-driven platform all along.
I don’t think that’s right.
Comes to mind also that Mastodon has had many years of headstart. How much of a slow growth does it still need?
