I don't think it's fair to say that product managers hate it. There are a lot of product managers and a lot of kinds of software. I've worked on complex enterprise software and have added enormous amounts of complexity into my products when it made sense.

I disagree that this is universally true. Alienating users is very frequently the right call. The alienated users never feel that way, but it's precisely the job of the PM to understand which users they want to build the product for and which ones they don't. You have to be fine alienating the latter group.
