I remember a Java One where Jonathan Schwartz was perfectly happy on stage that Android was being built with Java, even though it was pretty clear that he would have been even happier if Google had taken out a license. But then again, why would they have done that? Would they then have been associated with the stinker that was Java ME? Android broke new ground, building on top of open source, and that's how it should be ... provided, of course, that they share back.
It's pretty sad to see how all that ended up in a courtroom. http://arstechnica.com/tech-policy/2016/05/copyright-and-consequences-googles-andy-rubin-defends-android-to-jury/
