Its not clear to me that they can. Some of these problems relate back to activity hub.

And I just want to be clear, I think what we have currently based on activity hub are a great, proof of concept 1.0 (mastadon, lemmy, so many of the others), and that these lessons learned will feed back into activity hub 2.0, at which point there can be a material ‘taking back’ of the internet from corporate interests.

But right now, its not clear to me the current protocols or systems are where they need to be.
