Well, this is fascinating. ASUS hasn’t even released its Eee Pad Transformer yet, but it’s already put up for download the source code to the Linux kernel used in the Android Honeycomb operating system the machine runs.
The Linux kernel is under the GPL, which is a copyleft license. Asus is shipping Honeycomb which includes Linux. They have to “release” the Linux source code; as does every other vendor selling Honeycomb-based devices. I know licensing can get complicated at times, but this is pretty straightforward.
