Every business should be able to take some criticism within context and as long as its not abusive.
You want to keep most of your customers happy. So you should take on board criticism and suggestions.
My issue has been with Game MAker forums. Im pretty fan of GM but recently its like every topic i make gets closed with some almost rude and ott replies from mods.
They seem to decide for me what im trying to say in my threads, and usually take it the wrong way/meaning.
My last thread was asking them what they were comapring the cost of professional version to. As they say its very cheap. So i pointed out there were numerous free developement tools (which most people know!) Then they accused me of complaining about the price and then closed the thread, Its a good justified question. If i sold cars and said this is the cheapest car available, i wouldnt mind telling people what others cars im comparing to. When supermarkets compare prices they tell you clearly theyre comparing to tesco or asda or netto etc..
These guys are way TOO controlling over whats said on forums, even when you back up your questions. come on guys, if you cant take criticism or youre going to stop people asking genuine question you might disagree with is not good.
