The point I am trying to make is that when a game requires the use of Steam, Steam becomes a part of the game -- not just an optional addition.
So, when you are put into knowledge that a game requires Steam, you know that to play the game you will have to use Steam. This in my mind means that if you still want the game, you also support the use of Steam in the game. So it may not be that you necessarily want Steam, it is more so that you are content with it being present.
If you do not wish to support the use of Steam in games, you cannot just whine about Steam while playing said games. You have to show your dissatisfaction by voting with your money. That's what it all comes down to -- its your money that's speaking for or against Steam in games.
