I don't think the onus is on the gamers to shut up totally. Gamers, at least those who want to be taken seriously (like us here, we're a pretty decent bunch), should and usually do present their issues in clear and well thought out comments.
The bigger responsibility is on the developer to not react to your 11 year old gamer whining about his own lack of skill....or to the gamer who just dislikes that kind of game. both are pretty simple to spot. usually their sentences start "THIS GAME IS $&!~...."
The article is good in that the developers should have a clarity of vision and not depart from it. the article is not good in that it paints ALL gamers as whiny, useless, unreliable, and detrimental. That clearly is untrue. if we were that, FS2 would likely have been forgotten many years ago in favour of something with more sparkles... The real hardcore cares about their game, and wants the best for it.
