Define community, are you talking about the community of paying customers or are you talking about the BBS community? They are two different sets of people. The benefit to the paying community is that they receive a perk, they can post in the members only forum room where the none paying community can't. The non-paying community can continue the use all the other forum rooms as they currently do, unchanged. The benefit, all the posts in the members only room come from paying members, those players with a vested interested in seeing AH be as successful as possible. The wines, grips, and suggestions in the members only forum room would be coming from the people that are paying the bills at AH and are the only reason that all the other forum rooms on the AH BBS and the game exists.
AS it has been stated before. If this was to happen you would effectively isolate a fair portion of the BBS. Their opinions do matter, because they can give unique insight as to why they left or things that may/should change. Informing other players and HTC alike. Why wouldn't HTC want their opinions? When if they regard them, they could get some subscribers back, and potentially earn new subscribers. While I understand your frustrations of people who 'don't pay, so they shouldn't have an opinion', that really isn't a fair shake to them either.
If it really bothers you, just add them to your BBS ignore list .
