Yeah, so? It is the best restaurant in the world, from the point of view of millions of people who go there.
I personally hate superhero movies and McDonalds, but to say that these are incorrect or bad in some way is to cast a (probably class-based) value judgement on something that is adding value to people's lives.
They're bad if they make it harder to access more complex experiences.
This doesn't apply to McDonalds, because a McD won't automatically kill off more sophisticated restaurants within the same area.
It does apply to terrible movies and books, because more creative and original projects don't get made "for commercial reasons" - which is really just a form of corporate enshittification.
The issue isn't just that they're bad culturally - although they are. It's that they normalise conformity and creative obedience through the principle that the mass market is the ultimate cultural authority.
When a majority of creators self-censor because "This will never sell/get made/be published/be listened to, what's the point?" - that is a very dangerous place to be.
You don't need to burn or ban books to destroy the values they represent. You can censor them implicitly by making sure certain values, ideas, and creative orientations have no cultural presence.
