This may have been true at some point and is the conventional wisdom now, but it’s no longer accurate as pointed out by others in the discussion here. There’s a lot of pressure coming from anti-porn activists who seem to have zeroed in on smaller companies as the most vulnerable. OnlyFans and the PornHub parent company have faced many different attacks as well, including lawsuits and campaigns for age verification laws, but for whatever reason they seem to be immune to financial pressure. Probably because all they do is adult content, so they are willing to fight it no matter the cost!

(Note that OnlyFans did get attacked in this same way before and briefly attempted to pivot to non-adult content before rapidly backpedaling after a user and creator uproar.)
