A tiny fraction, but I suspect many more have tried and been put off by personalities and politics. Quite a lot of better known projects are plain offputting to get involved with. I know far more who've put out a few bits of solo programmed freeware or shareware, or pushed the odd utility to a library though. Of all the places I've worked, none have encouraged or suggested contribution, but many have used open source in the business.
