In today's news, the terms of the Android SDK has changed. However, it seems it was not open source in the first place. What's always interesting though, is the discussion it spurs, with insightful comments on Slashdot.

"Freedom is not (just) a matter of principle. The reason that people take your freedom away from you is because they want, later at their option, to be able to take other things from you that would naturally be yours. Microsoft locks people into proprietary licenses because they know that, after a few years of using the OS they buy from them you will need a new computer and a new system, either because your old one broke or because an associate wants to do the same things as you do already. Normally, if you were allowed your natural right to copy things you own, you would just be able to copy the old one and that would work fine. By taking away that freedom, Microsoft is able to take away your money from you again later for nothing more than you could easily have done yourself if they didn't interfere with your copying.

Google's aim here is to make life difficult for competitors such as Amazon and the Chinese Android clone makers (not that these will care). This allows them to interfere with the free market for their own benefit. For programmers reading Slashdot, that means that, instead of being four or more potential developers of mobile software you can work for, Amazon, Google, Apple and the Chinese, there may well only be two: Apple and Google. With the possible exception of Jolla and Ubuntu, there is almost nobody else in the market who could consider competing. For people buying mobile phones would mean that, instead of having widespread choice from different vendors, everything would go through Google or Apple.

This is one of the key reasons why licenses such as the AGPLv3 as well as free software foundations which can provide a neutral holder for coyprights are so important. Look at how FreeBSD development has been absorbed by Apple even though it was supposedly "Open Source". Without strong copyleft licenses the only choice will be which set of chains you wear. Once you are wearing those chains the only choice will be to give the mobile vendors what they want to take."
