Somehow I suspect someone has missed how private companies work. When they sell several million units, it's not exactly feedback that something is wrong...
That attitude is exactly how companies go awry. You can't release one product in one style and take its successful sales as a wholesale endorsement of your design decisions. I could've told you Civ 6 was going to sell huge before we knew about the art style (or heck, before it was even announced). You have no way of knowing how many of those sales are to people who love the art style versus people who are buying in spite of it - or for that matter, how many *more* sales you might've gotten with a different art style.
That said, I'm firmly in the category of people who (a) love the art style, (b) would've bought in spite of an art style I'd hated, because Gameplay, (c) as an artist myself, appreciate it's not what art style they chose but how well they executed it, and (d) think these petition people are stupid.
