And on the other side, if you're someone who gets raised to a public personality for your liveliness and lack of filter, you're likely to step over the line eventually.
One of the best points I've seen was that Youtubers have a lot in common with talk radio hosts. When Howard Stern said something offensive, it was a bit rich to act surprised. He was paid to be shocking, he did better the harder he pushed on the edge of acceptable, and so of course he eventually went too far. Everyone from PewDiePie to Penny Arcade have run into the same issue.
(Under this framework, JonTron is a fundamentally different issue - he doesn't seem to have been looking for views, just melting down.)
Howard Stern is a terrible example: his advertisers knew exactly what they were getting.
PDP, unless he's stupid, should have known what DISNEY wanted. And it's not anti-semitic jokes, particularly following repeated use of Nazi iconography in his videos.
PDP was popular before Disney became involved, if Howard Stern's advertisers knew what they were getting then Disney should have known as well. You provide Stern an excuse but then deny the same excuse to PDP.
Notably Stern's employers and advertisers seemingly didn't know what they were getting, as judged by their decision to drop him for racist comments. Maybe they should have known, maybe they knew but figured they could profit and then drop him when he screwed up, but they did hire him after his success and drop him later.
You're right that it exactly mirrors PDP's situation: off-the-cuff, inflammatory content creator partners with advertisers, does something extra-inflammatory, gets dropped by same.
