I think they were saying, if money is free speech, and racist slurs are free speech, and anti-semitic conspiracy theories are free speech, then the quality standard for something to be free speech is low, and any mildly sympathetic individual or organization would put their own standard for free speech higher.

I think we are mostly in agreement?

The "US Standard" generally means the standard by which the people of the US value the concept of Free Speech, which extends beyond that of the 1st amendment. We the people of the US codified our position on speech in the 1st amendment of our governing document to ensure that our government would never infringe upon our most vital right as free humans.

This however does not in anyway mean we believe others including large corporations should have the right to infringe upon said rights simply because "its a business"

There are many avenues one could seek to hold Joynet and others like them that proclaim to be open to all in their advertisements then reject many they disagree with. First and foremost would be Truth in Advertisement laws, Fraud, and other legal regulations which if they were properly enforced these companies would be clearly violating

No the "US Standard" of Free Speech is not just about government censorship, that is ignorant and naive view of what Free Speech is as a concept. Free Speech is concept where by a person is free to express themselves with out fear of censorship from either government or society at large. Free Speech today is under massive attack not by government in the US (yet) but by society at large.
