I imagine Apple already complies with whatever they need to comply with in order to make the Chinese government happy.

No, we absolutely aren't. The Chinese government has ensured for decades now that foreign businesses have only tightly controlled access to the Chinese people while Chinese-owned (i.e., easily controllable by the Chinese government) businesses have advantages not given to outsiders. (And those outsiders need to open up a Chinese subsidiary that is majority-owned by Chinese investors/companies.)
On the other hand, most Western countries have given Chinese companies near-unfettered access to their markets.
If anything, this TikTok ban is actually making things more equal, if only by a tiny bit.
