There is nothing wrong with making money, certainly not when the way you make money is perfectly acceptable. I don't see how selling Tremulous discs comes even remotely near any kind of 'lameness', 'cheapness' or 'bad-hearted intent', but hey, most people are as selective as fuck when it comes to whining.
You live in a world that is brimming with products that are of a questionable origin, and you spend your time whining about some person selling Tremulous discs, as if he/she is doing something morally unacceptable.
I suggest you get your feet back on the soil you are supposed to stand on, open your eyes and look at the world around you. Soon enough, even people like should realize the retardation of their ways, and will hopefully project their excess energy at the real problems in this world.
Fucking hippies.
