This kind of makes me sad. I feel like this is a terrible trend that is/has basically ruined gaming.
The way I see it, making a game is art. I want to make games to express my ideas, and my feelings, and I want to do the best I can to convey those feelings and ideas in my games. The moment you start seeking player feedback for your game you are no longer making art, you making a product. I suppose that is all well and good if your goal is only to make money (although I highly suspect that this often has unintended and sometimes opposite affect).
Seeking player feedback is like Michelangelo asking random people on the street how he should have carved the statute of David.
This is my art, this isn't a collaboration, I don't have any desire at all to sink, time, effort, and talent into someone else's ideas, especially when they aren't willing to sink any time or effort to do it themselves, they just want to sit back and call the shots without having any skin in the game at all.
This seems like a loose/loose situation to me, the game often ends being worse in the end, and the artist becomes a cog/slave to the masses (who often don't have the foggiest clue of what they really want, or what makes a good game, because they aren't putting real time and thought into how the mechanics will interact, what is technically easy or hard, they just trow out "It would better if it did x, y,z").
