To people asking why Stewart would make a show for Apple in the first place, in some circles Apple is seen as a basically ethical company. I won't comment on whether it's valid to see them this way, but they make a lot of comforting noises regarding privacy and green tech. Plus, being what amounts to a broadcaster, one might expect them to keep their hands off shows being made for them.
What I find interesting to think about is, if China is able to apply pressure on Apple concerning shows made for them, what kind of pressure could they have over TikTok?
