@esther It's the same here. If the people in important positions of development and administration decide that they'd rather sell the soul of the fediverse to Facebook, too bad. Yes, individual admins can block, yes, the software development could fork, but that still needs people both able and willing to do this.
It's also not just the fediverse. Wikipedia and AO3 are both non-profit, ad-free, and both have internal drama. TV Tropes (which is ad-funded) has drama. That's just the internet.
