Oookay. That's a lot to go through. I'll do my best though on points I feel need responses...
First:
"tried to deplatform others" Why do you have a problem with this? Isn't the point of this list to boycott these creators and make them go bankrupt? That's pretty much the same, you're telling people "these are the people I won't buy from, and here it is for you to use as a reference.".
The differences here are two fold. First, this is not exactly a boycott. Heck, I purchase books from Onyx Path Publishing, armed with the knowledge of what to expect from them. On the matter of Evil Hat specifically, well, they make FATE which is free. For that, they at least earn some respect from me. Second, there's a difference between I don't like something, and It shouldn't be allowed to be sold. This list is more guilty of the first sentiment, while Evil Hat is guilty of the second. Note the lack of calls to go to One Bookshelf to have these people pulled. They are allowed to exist.
How is it racist? If consumers want more hot women in art pictures, a company will draw more. If consumers ask for more diverse creator, how is it anti-consumer to not spend money unefficiently? That's basic Capitalism, babe.
Indeed, but basic capitalism has had its limits for a while. One of those limits is that you are not allowed to decide on other people due to protected classes. Race happens to be one of those classes. In this regard, Roll20 is acting in a manner that is textbook racism. Heaven knows the torches and pitchforks would be rightly out if the script were reversed. Furthermore, drawings are generally additive. You can always draw more. Dealing with actual people, though...That's exclusionary by its very nature. You turn people away. Doing so because they are insert race here is not okay. Actually, that also applies to this bit too.
Hires favouring trans, people of colour, IDIC, and other minorities.
This is their actual issue, I think. The rest is really context. Once again, hiring discrimination is not okay.
Generally speaking, a number of the editorial comments on the list tend to be context, though some people may find that material objectional. They shouldn't in the case of the various identities of authorship and all, but published work definitely makes that list.
Finally, I'm not sure if the multi-post was necessary. It's a little spammy.
