Social media is like capitalism. If your way is the infinite grow, you end with entshitification for both. You need to have a limit where you balance quality and quantity.

It's why the steep learning curve isn't as bad as people like to say. It's the limit to keep the quality high enough. If you have a lot of new player making it easy to join, you change the equilibrium and entshitification begins.

But, fediverse is in some case protected. If the new player has its how instance, the others can defederate. It's what is already happening.

I'm part of a minority and I use Mastodon on a dedicated instance. We defederate of some very specific instances to keep our safe space and keep entshitification away.
