As long as no one is insulting someone directly everything is fine i think because as a consumer you should be able to be constructive whether it is criticism or praise.
But if you react like this it would not be a wonder when there is a CoH3 and no one buys it...
And yes BF3 is a good example for really good support. Think about it.
PS: Why is the pre-order Content for normal pre-order missing now? There was a Special camo for example!?
