I hear what you are saying. At issue here is whether Facebook et al are now the “public square.”
If they are they have to have reasonable accommodation.
And I agree. Technology has moved us into a new world. Someone started a new service in their dorm room and it became wildly successful. Where’s the line where it crossed over from “theirs” to “ours”. And that line is going to become more hotly argued as technology advances I’m betting.
