|Android i a Linux system developed by Google and by far the most popular OS for mobile phones. Now Google is very generous about this here:|
Aha! So that is why Google created Android and generously made its source code open. I have got it now. Silly me I thought Googles generosity, or lack thereof, did not matter since the GPL license of the Linux kernel demands that anyway?
Still this is one of the greatest Linux successes ever and that is a good thing for Linux as a whole. And boy has it been proven that Linux is commercially interesting. You can make a sh.. load of money on it! Google has!
