While it's true that Linux is an open-source operating system, some folks have the perception that "Linux" and "open source" are the same thing. I don't know where this comes from, but it can't help that that US-based OSDL (Open Source Development Lab) is funded by vendors to promote Linux as an operating system. The new Open Source Consortium being launched in Europe may help to correct this mis-perception and draw attention to the great diversity and portability of open-source.
