Without commenting on the merits or lack thereof in this case, I think it would be useful to give some more information about the FSU: https://en.wikipedia.org/wiki/Free_Speech_Union
What a surprise that this crew seems very much in this boat.
I'm not issuing judgement on if paypal is in the right here or not (although my knee jerk reaction is that they are not), but the age-old "they're pedophiles" canard is well past dog-whistling and into trainwhistling at this point.
I try to follow this myself, but I do find myself giving exceptions to specific touchy subjects. For example, I don't understand how to approach a touchy subject where open discussion actually drives away people and therefore makes it an echo chamber.
For example if a gay person left a community because people were openly discussing whether or not gay people are pedophiles and advocating for the castration and torture of gay people, and that the advocating for castration and torture of gay people wasn't being shut down, I honestly think that's a totally reasonable behavior on behalf of the gay person. And I honestly would disagree that this created anything even remotely resembling a "forward path" direction.
But, in abstract, I still believe we should openly discuss touchy subject matters. I just find myself constantly running into actual application where I disagree that openly discussing a specific matter actually benefitted anyone, and found myself agreeing that the community would be healthier if specific topics of conversation were shut down.

Try writing your own article and submit it to their site. They won't publish it unless it's some right wing conspiracy bullshit. That's their right, of course: it's their platform and they get to choose what gets published, and anything they don't agree with gets "cancelled" for anyone who wants to use that moronic term.
But then they try to turn around and get their own crap published on other, more credible platforms, because otherwise nobody will read it. And of course, these platforms, such as universities and newspapers have a reputation to protect, so they aren't going to publish a bunch of nonsense.
