Oh, also, one thing people never discuss when talking about hosting your own server: legal liability. This is a very real thing that you absolutely should not neglect.
In Mastodon, everything is lumped onto a single server. You carry every type of legal liability risk. Your server scrapes in CSAM, for example - whoopsie! Your server scrapes in copyrighted music. Your server scrapes in GDPR violations. E.g. while your *users* can cause you problems, problems can just be dropped into your doorstep just by caching. You also are also classed as a Hosting Service or Online Platform under the DSA, and unless you can get a qualified exemption, you have to provide transparent notice-and-action mechanisms, points of contact,and annual moderation reports
This does not happen with a PDS in ATProto. They never download other PDS's content; the only risk is your users. Under DSA, since you have no consumer feed, discovery algorithm, or public facing portal, you're a bare "Hosting Service". You're basically NextCloud. Not subject to Online Platform requirements.
What about the relay? Also no! They're non-archival. They don't download content. No CSAM, no GDPR vio, no copyvio, etc. Classed as a "Mere Conduit" under DSA. Zero issues.
Labelers, also none. Do not host content.
The only thing having any risk is the AppViews. But even still the risk is reduced. For example, if CSAM comes up, you're mediating it, but not hosting it. You do however get subject to the "Online Platform" category.
