I mean, isn't part of the issue that it's "too late" to "vote with your wallet" in many cases?
Like, your Radiohead example, people are saying they don't like Kid A (i.e. people with no taste) probably already bought Kid A, didn't they?
And I think that's true of like, a huge amount of criticism. People pay for a thing and then don't like the thing. So it's perhaps confusing the argument to mash them in with this other group of people, who haven't bought the thing, and are insisting that thing shouldn't exist.
There's also the slightly complicated issue of "You're doing it wrong!", wherein a product is inevitable, but you dislike the way it's been done, but can do nothing about it aside from not buy it. Like, you can definitely rag on me for this, but I strongly suspect that WotC are going to bring out a Planescape-y book, and also that it's going to be as bland as butter & plain white bread sandwich (where the original Planescape was a bizarre banquet probably involving a lot of things a lot of people didn't want to eat!), and I'm pre-emptively inclined to be annoyed by that because it's going to set the tone for Planescape for at least this edition, and likely for the rest of eternity. And you can say "Well do it right yourself", but dude, if I do that, I may well get sued, right? Because that's how IP law works.
