The McDonalds analogy is actually better than you think - imagine by some market quirk most of the restaurants in your city hired chefs that suck at their job. Because, say, The American Culinary Institute declared food is not supposed to taste good, it is supposed to send the right message, and the taste is secondary. It's not like the food isn't edible or harmful anymore - it still delivers the nutrition, and still kinda edible, but sucks. Ignoring the fact you could cook for yourself - let's imagine for a minute you have to dine out - what would you do? You'd go and eat sucky food. And since you do, the business model is provably working. Maybe if the whole town agreed to not eat out for a couple of months as a protest against sucky food, it could be changed - but what are the chances of that actually happening?
I didn't write the McDonald's thing, so I'm not gonna try to contextualize it.
I also enjoy the cinema but I only go when there are films that I find interesting and worthwhile. In my specific case this means that over the past few years I've seen Parasite, a showing of the original Alien, a few midnight B-tier horror movies, etc. I don't get to go to the movies as often as I would prefer but the alternative of wasting my time on films that I don't find attractive while simultaneously financially supporting an industry I disagree with seems obviously non-viable to me.
That seems like another odd assumption to make. It doesn't need to be based on individual choices, social dynamics drive plenty of decision making [1]. FWIW, I've only seen 1 new movie this year, and I only plan to see 1 other, so it's not like I disagree with you at an individual level. That's not how it works out in the larger population though - for many people it's their leisure activity of choice.
