This made me wonder, is a conference's choice of which speakers to schedule an act of free speech by the conference organizers?

Is regulation of access to a public square a violation of free speech? What about shutdown of a given public square, knowing there are other squares?

They have enough tanks to squash as many people they'd like in as many town squares as they have, just like everyone saw them do in Tiananmen square.
