Bluesky has reply-gating (you can set who can reply to a post, like people you follow or a given list or no one) and is now testing out post-publication reply locking.

I just want to yell for a second about how humane and consent-forward these features are, especially after seeing some people here losing their minds when someone asked for gating recently because they felt (alas, not a paraphrase) entitled to always be able to respond.

This might be a good indication where effective contributions to the topic are focused:

Apologies if mine is perceived as a right-to-reply thing. I truly believe it is constructive, and I have no way to implicitly know if you appreciate getting this apparently new information. For better or worse, this is what the available affordances shape. My understanding is that some types of replies are more desirable than others, and particularly for factual replies, this has little to do with authorship.
