> What if we had a standard way to let users themselves build up and share their own views of whether other users, messages, rooms, servers etc. are obnoxious or not? What if you could visualise and choose which filters to apply to your view of Matrix?

The closest to actual deplatforming is:

> Admins running servers in particular jurisdictions then have the option to enforce whatever rules they need on their servers

But honestly, in a federated system I always assumed the server owners could do that. As long as it's not mandated from on high by the Matrix team, anyone can host whatever they want by setting up their own server.
