Prpbably the chain of reasoning OP follows:

Watch Movie -> Studio gets Money -> Tom Cruise gets Money -> Tom Cruise donates Scientology Money

I understand why they wouldn’t spend money on it, not watching it entirely is then just a more extreme form of this where you also don’t contribute to public interest in the movie

I don’t even find him to be a good actor, too generic and cookie cutter. Not my cup of tea. I watch movie es to see different characters, not him doing the same thing. He WAS good, but all his more recent stuff is just the same role with a different name.
