We knew in the aughts that this was going to be an issue when the charging companies defunded Wikileaks and Julian Assange¹ and were allowed to do so, defying public accommodations laws.
1. Yes, Assange is a git and a Russian asset (or at least has been before) but he did serve as a whistleblower against evil shit done by Bush and Obama administrations and the general aristocratic corruption at play in US federal politics. As with Chelsea Manning, he embarrassed politicians using their positions of power inappropriately, revealing that the state was not serving the public. Incidentally, ACLU in its early years was funded by USSR to cause trouble against the US state (which it was doing anyway and still does), which makes it historically (and debatably) a Soviet asset. Strange bedfellows and all that.
This is a tale that keeps repeating itself, and is why protections by the fourth, fifth, and sixth amendments of the Constitution of the United States have been carved out like a holiday turkey by the US Supreme Court. We found it easy to deny unreasonable search and seizure protections from major crimes suspects, only to find that every black citizen with a gram of cannabis now no longer has those protections.
So it is with monopolies that decide they can be selective with their accommodations.
If we can't pressure the transaction services to obey public accommodation rules since they have monopolistic power, it may be time to circumvent the issue, and support black market tactics ( Archie comic and bag of sawdust, $20, comes with free incest porn! )
These days, when discussing the usenet alt.* heirarchy, its acronym ( Anarchists, Lunatics, and Terrorists ) is now considered a backronym, a joke. I was there, and it belied a serious point: The worst of us deserve free speech, as per Larry Flynt, knowing that Hustler magazine is legally published in all its (raunchy) glory means that whatever you're releasing to the public is safe from moral guardians and critics because they have worse stuff to shout at.
But we're in an era of book burning, which means those would-be moral guardians are emboldened to try to reshape society in their image, in contrast to the principles of liberty and free thought. And soon ICE will expand its POI list to include liberals and wrongthinkers.
It may be time for bricks in windows and direct action against high-ranking company officials, but such behaviors carry high risks of consequences. So be careful and thorough.
In the meantime, write petitions of your grievances and sign those others have written. And remind them at this moment the public presumes petitioning them for redress of grievances will be acknowledged and acted upon. And if that turns out not to be the case, the outraged public will not simply disappear and keep to its place.
