now this is just the beginning; for they will need to throw money at their fork to make sure it's successful. And isn't that ultimately what this was about, money? Now Amazon has the opportunity to hire the core engineers to contribute to the TRUE open source project.

Everything by design as intended. Go Amazon.

Don't start an open source projects if that's not what you want to be. Or did you forget what made you successful to begin with?
