That varies by group and game system. If you're playing in a published setting, the setting exists in the minds of players and GM - usually not congruent views across players, either.
Sure, published settings already exist as ideas. But the but about congruency is, I think, why the term “shared fiction” is so important in this discussion. And that is brought into existence through play.
This is NOT congruent with my experience.
Players often have to give in to the GM's view; unless and until the group disintegrates, the only person who's view matters is the GM.
I disagree here, although I’m not sure if you’re asserting the above or only pointing out that this is often asserted by some folks.
I think @Campbell included a bit about the GM introducing something, then the players asked some questions, and then the GM revised what he had introduced. An example of players “vetting” the GM’s ideas, which is something that does happen, although far less than a GM vetting the players’ contributions.
