Indeed, it might be GPL source code, but it's proprietary code in the sense it doesn't follow any standard. A single driver for three distinct I2C devices isn't exactly smart, and many values appear to be hardcoded for the exact Thecus N2100 hardware, so the code is hardly reusable. I admit I don't understand companies who base their products on Linux, and play fair by contributing their code back to the comunity, but in a way that it'll never get merged. It means they spent efforts inventing interfaces when standard ones existed. It also means they have to maintain their contribution by themselves forever, and that their contribution won't integrate well with the rest of the Linux software. So in the end the user doesn't benefit at all. -- Jean Delvare
