How is it a free speech issue when someone kicks you off their property? It has nothing to do with speech so why would the first amendment be involved?
See the linked tweet for a more lawyerly argument in defense of shadow banning. The question before the court may hinge upon whether or not shadow banning expresses a message.
(I am not commenting in this message on whether an HN issue may exist or should be let go. On those matters, I am still reading.)
