They could potentially escape 1st amendment issues if there was a way to keep posts reply-less.

A post marked "non-repliable" would then simply not show any replies on instances/clients that implemented this.

Of course, if they'd like to actually interact with customers, it's a loss.

There's a really good discussion of how ActivityPub handles replies here:
