So if I'm trying to use this in my proprietary product, I can either a) use it and open up all my code, or b) use a better-licensed, MIT/BSD/APSL2-compatible code. I also might point out, as a person working on a proprietary service, it's in our interest to contribute upstream. Who wants to maintain compatibility patches? It's in EVERYONE's best interest to have solid, open infrastructure used by everyone (yes, even evil closed companies like google)
