management only cares about the numbers. we are linux users, a mere couple % of the market. do you think they care about every single one of us?
If you don't like AMD/ATI linux driver support then email the AMD/ATI management and sales people and if you get fed up waiting and change to another graphics card then email AMD/ATI management and sales and tell them why. It's no point taking it out on the developers they can't get more resources to work on it , it's the management who can do that and they will do that if driven by sales.
