The hypocrites are doing the same thing as what they are against with exclusivity. They only want the game on Steam. You probably heard of the typical warcry of "If it's not available on Steam, it's not a purchase."
Instead of a developer doing it, it's all the fanboys of Steam forcing developers to release the games on Steam. Most of them have hundreds of games they collect but never played on Steam so they want everything to be in one service for easy access.
