I agree, Headroom's rates are a good resource. So are the opinions of everyone on Head-fi. Both should be free to express those opinions of course. I think folks are reacting negatively not to any particular opinion being expressed, but to the manner in which the opinion was expressed. If the vehicle was respectful, the worse that can happen is that everyone respectfully disagrees. If the vehicle is heavy-handed, there is a high possibility of flame wars breaking out, which everyone is eventually sorry for when heads cool (unless you just like flaming in general, which is a whole other ball of wax).
I actually think everyone is saying the same thing here - that everyone should be free to say what they like, and they are also free to listen/read while maintaining their own opinions. Anything else is just human nature busting out, for good or ill.
