Right. They don't. But they seem to think they can send de-auth packets that effectively say to third parties, "I am going to disconnect you from this network". That is at the least -implicitly- saying "I am claiming this SSID, and I am willing to use power/technology/tools to enforce this, whether you like it or not, whether I have the right to or not".

I never said the FCC was involved in enforcing trespass statutes. If there are people on your private property behaving in a way you deem unacceptable (even if legal), then the solution is to remove them from your property, not for you to illegally interfere with the use of the spectrum. That's vigilantism.

The Corp HQ example seems to work because there are clauses that surround intentional deception and the risk to security that could come there-from. When CorpHQSSID access points de-auth packets to an unauthorized access point using the same SSID.

That -wasn't- what was happening here. The convention center was saying "I don't care what your use of the wireless spectrum is, your hotspot, whatever, I'm going to interfere with it so that my SSID is the only one usable (oh, enter your credit card number here)".

Your contortion of logic, willful and disingenous ignorance of contradictions and interpretations don't change these facts. The issue was discussed many times, many lawyers were involved, and the outcome was decided - whether you think it should be or not (your perfect right), it -is- illegal.
