That's what I meant by sane defaults, personally.
I already don't see any worse in my global feed than I see on most social media, but my global is limited to three paid relays, one of which I operate.
Relay operators do have a choice, and they should exercise it. As long as users are able to add and remove relays easily, that seems like user choice and power. Good relay operators will be rewarded, bad ones may find themselves on jail. Ultimately the user's choice whether to use them.
But, that's no different than what we already have. Ultimately this is going to be a question of Clients needing to run their own moderated relay as a default for store guidelines, no different from how fedi clients have done.
