We probably won't agree on this point, which is fine. There is a subjective assessment here. Again, I would argue most RPG companies (that is small to mid-sized companies) can't operate successfully without being on OBS. Just my point of view, but I am not seeing real viable alternatives to OBS as a publisher myself. There are alternatives but they aren't viable alternatives. They are mainly going to work out for larger companies, companies with unique levels of reach due to other factors, but your average small to mid-size RPG company is not going to have an easy time outside OBS. And the reason that matters is their content is going to be impacted by whatever policies OBS sets. Which means if you are an RPG consumer, this is very much a question of what kind of RPG content landscape do you want (and I can't answer that for you, everyone is going to have a different view). Personally I would like for publishers to be comfortable with the same degree of creative expression as you have in movies or novels. Because I want to see people making stuff like that. And myself, I don't make anything particularly objectionable. But I occasionally want to throw in serious themes or something shocking in the way you would find in some horror movies. Some of those guidelines do make me second guess many choices I make.
But if you think there are viable alternatives, and they don't have an outsized impact on things, fair enough, I think it is best to just agree to disagree on that point since we are probably unlikely to arrive at a new understanding from anything you or I say.
