> Different things are mashed here. Public square implies public (Gov owned) property. A Gov official that posts a comment on my blog wouldn't transform my blog into a Gov owned entity. It would be a disaster if it did because it would become trivial for any Gov offical to seize my entire blog.

The argument is the government is mixing in with these social media behemoths, especially Twitter. It's more than some official using your blog. If you are kicked off one or any of these networks you basically lose access to your government officials and companies that choose to do their business there. There are no legit alternatives, these social media behemoths are so big they are becoming a town square for communication. They should be regulated as such.

I said baker. I was alluding to the case that forced the Christian bakers to bake a cake for a gay wedding.
