Hollywood doesn't care. The only ideology is "will this sell tickets." The most likely outcome is Hollywood will film patriotic block busters for both the US and China.
Anyone can distribute a movie. A clever 12 year old who knows how CDNs work can set up global distribution in their spare time for fun. This is a problem. Being reduced to a source of funds in a creative business is almost guaranteed business death. In the past, total control over the distribution chain allowed movie publishers to manipulate things to be profitable. There is a very inconvenient fact that businesses in the creative space have to deal with (although they never admit it, not even to themselves) : the public response to any creative work is random. Truly and perfectly random. There is nothing you can do to improve your odds, they remain even. Sure it seems like there are things you can do to bend things in your favor, like use big-name stars, throw a lot of money at the project, etc. But run the numbers. It doesn't work. Not even a little. For every Titanic or Avatar you have a Waterworld or an Ishtar. The book 'A Drunkard's Walk' has a couple chapters about the creative fields, book publishing and movie publishing specifically, where they go through the research and the numbers. It's just random. The audience is different every time, so it makes sense that the end result is randomness in the theaters on opening weekend and right after publication.
So what do you do if you're a business who wants to make money, and your industry has changed from being this thing you could control and make profitable, kicking your failures aside as fast as possible and keeping your successes around for as long as possible, to being mostly a game of chance? You lean on the little control you still have, of course, and movie companies definitely do that in the theaters. Good luck catching a movie after opening weekend if not many people showed up that weekend. Maybe go see Avengers: Endgame for the third time? But that's pretty limited in how much it helps. It still hurts badly to drop $10 million filming a movie and then having to kick it to Bluray or streaming after 4 days in cinemas. What you do is play it as safe as humanly possible. You don't take any chances. You make sure the movies have big names, have big special effects, have big budgets, and you definitely don't do anything that would ever risk limiting your market whatsoever. You don't mention religion, you stay away from politics, you absolutely prostrate yourself at the feet of anyone and try to make the most broadly palatable thing you can based on aggressive focus-testing, analytics, etc. You go wholesale soulless. It's the only option, really. And it probably still won't work. It will probably still catch up to them eventually. Because you can't escape the numbers, and big chances even on the safest bets at the craps table is still gambling.
The creative work will continue to come from independent filmmakers, and their destiny is bright. Not billion-dollar Avengers: Endgame bright, but bright enough to keep yourself warm beside and make a living off of. No longer do they have to keep their fingers crossed and hope Weinstein buys the rights and puts it on a shelf somewhere to prevent it from competing against him in the box office. They can sell to Netflix or Amazon or Disney or just "publish" the thing themselves. And a niche market is fine and survivable.

How would it be possible to "play it safe" if movie popularity was random?
