similar to ILUG-Delhi, ILUG-Chennai has been running on a high "enthusiasm-fever" and has been supporting users to run non-free software like Oracle and Opera under "Linux" and has also been supporting other non-free Unices like Solaris and such. The main misconception being, most think anything UNIX is "cool" and anything non-UNIX is non-cool (and, free Vs non-free does not sell much in there).
This is what tends to happen with Linux User Groups, and there are systematic reasons for the tendency.
There is no necessary logical connection between the group's choice of values and the name it calls the system. It is certainly possible to call the system "Linux" and believe as strongly in freedom as any of us do. But the values usually associated with the name "Linux" don't give priority to freedom, and people who hear, think, and talk about "Linux" tend to pick up those values. Any group that uses the name "Linux" will have to make strenuous efforts not to be carried away by this tendency.
(Even if the group uses the name "GNU/Linux", it will still require an effort to resist the tendency. But mentioning GNU will help.)

I hope that these words are meant as satire. To seriously think such a thing (about anyone) is dangerous for your mental equilibrium, and if it happens in sufficient quantity, threatening for mine as well.
