Open Source vs RMS
I think Open Source is specifically a campaign that opposes RMS/FSF/Free Software, and I fully support that opposition. the main problem is RMS: he has this huge axe to grind, not just about keeping code free, but about taking credit, and about rubbing all our noses in his silly communitarian politics. the discussion is meaningful only as long as it concerns issues like whether APSL's termination clause is a problem. when the discussion is about "Linux" vs "GNU/Linux", someone is being an ass.
but all this licensing brouhaha is misdirected: the issue that must be confronted straight on is software patents. they're plainly wrong, and more of an abomination than any license ever was. software copyrights are, on the other hand, plainly right, for the same reasons that novels, and even yellow pages are copyrighted. if we solved the software patent problem, all these varieties of source license would be moot: copyright protects against plagiarism, and what should be free, ideas/algorithms/interfaces, would be free.
