Rather a different sort of product though. Can you see TSVN going into
routers or DVD players? OK, that's just plain silly, but really, the
possibilities for commercialisation are a lot more limited for a Windows
Linux is a tricky example. You can add proprietary drivers and apps
quite legally without making source available. Only if you modify the
GPL'ed distribution do you have to provide source. I guess if you make a
driver based on a GPL skeleton driver you are in a grey area. I'm not
saying violations don't happen, just that it is perfectly legal to make
commercial products which include some GPL code and some proprietary.
