The USSC has held (quite rightly I might add) that just because a corporation owns a ‘town square’, doesn’t give them the right to stifle speech there.

"....just because a corporation owns a ‘town square’, doesn’t give them the right to stifle speech there."

So, you are inferring that a corporation can't regulate speech within their business confines? Or you can't regulate speech within your home? Or a school can't regulate speech withing a classroom? Etcetera.

Perhaps you should give the issue a little more thought.
