Something to keep in mind: Google was never really interested in the idea of "open" — yes they love "open" when it helps them, but it's actually a very opaque company which has a "my way or the highway" mindset. Honestly I prefer the honesty of companies like Apple that don't pretend to be anything but a huge company.

But chalk it up to a good learning experience! And be glad that you didn't start to make real money, hired employees and then watched it all implode in a minute because of a small call at a big company.
