I'm sorry, but saying that an indie developer should have the strength to hire more people and make more stuff themselves is a bit unfair. I, for one, have a full time job, a family, and not a lot of free time. Still I want to make games, still I have story ideas that I want to make into games. What's wrong in using assets that are free to use? Where's the problem on giving the right credit? Most people don't realize that even big companies use assets from other sources from time to time. But we little developers should be able to live without?
