I don't think the fans want adds flying all here but then I can only speak for myself. 
Personally, I find web advertisements annoying. Someone would have to pay me
a lot before I ever agree to putting commercial ads on this site, and I doubt the revenue people get from having ads is very much at all.
Regarding working for free, legally, we're not permitted to generate income off of Sierra's intellectual property with our current license. However, just because one game is free doesn't mean all future games we create will be as well. Once we start working on our own original titles, we'll have a lot more freedom to commercialize. Also, money isn't everything. We're all gaining valuable work experience that we can use while seeking employment and portfolio building.
