In all fairness, the people that ventilate their criticism are the ones that pressure Relic to pressure Steam to make things happen. The likes of OnkelSam, Rogers etc. are not exactly helpful in developing and improving the game, because their contentment with the current pace of the development does not speed things up, nor does it give the Relic developers an idea of what needs to be changed/added rapidly.
You couldn't be more wrong. We give tons of critical feedback directly to Relic, you just don't see it.
