Pushing for enforced common carriage (Title II style) on PDS operators misses the point of portability and competing providers. Those obligations only apply where users have no real alternative.
If you can switch PDSes or self-host without losing anything, operators get reciprocal choice too.
Take that away and you don't achieve neutrality; you just swap voluntary communities for coerced ones.
Mutual and multiple selection is the real check on power here.
