The fediverse has some resilience built in. As users have a back up account. As an admin with concerns of government control, have a playbook to be able to pass off control of the instance to another admin in a different jurisdiction and that they can restore the instance to a new provider from backups.

As for stopping corporate interference: making sure bad actors like meta can’t federate, good moderation practices, and anti bot defenses. Intelligence sharing between instance admins, cooperation not competition.
