Well yes, if you write a book like Asimov wrote Foundation then there is no chance that it would get published as a new novel today. Tastes have changed in the many decades since he wrote it....if Asimov wrote the same story in 2023 it would read very differently and be more character driven, and probably be 2-3 times as long.

If you don't like it, then don't read it. It's still considered a classic sci-fi novel regardless of your personal opinion of it.
