Specifically in the context of this post you cannot be forced to collect any data on users or be prosecuted for not collecting because you are not hosting accounts, they are on-schain. Fedi is a very different type of platform and not really a direct alternative. Bastyon is trying to compete with twitter mainly IMO.
You do not get any special access or control by hosting a server because it is just a node that relays data. This makes the network more robust and faster as a user’s app will connect to the fastest nodes for a better experience.
