Or the facts of every circumstance matters a lot more in how the law is applied than you are willing to give it credit for.

A telecoms company like AT&T is subject to common carrier provisions and regulation by the FCC under the Communications Act of 1934.

If a landlord wanted to prevent you from putting up signs on the property, they probably can put that in the lease agreement but their free speech interests and property interests while still dominant are compromised to an extent as well by having rented the property out to you, but not to the extent that your free speech and property interests (like your personal property) are entirely compromised either. Their ability to evict is dependent on jurisdiction, but such a case would likely turn a lot on the facts depending on the jurisdiction.

Dress codes however can be arbitrary. You can be excluded from a club because the owner doesn’t like your shoes, and yes, that’s legal. Their property interest in this case entirely trumps your free speech interest. Having strong property rights is in part why we are a free nation, but sometimes when there are clashing interests, someone’s interests are going to win out and 9/10 it will be in favor of the property owner’s interest.
