I think that a lot of companies are very aware that their film or tv show is crap and simply build it into the budget that they are going to spend such and such millions on a disinformation campaign

I think the same. Faking reviews and imposing the show/movie through social media.

Learning new things, like new ways of marketing and stuff, is good but it would be great if they also learned new ways of making good shows/movies. I don't see that's happening.
