Some people use it because it's free, some because it's open, and some simply because it's not Windows nagging them. With every movement that gets popular you'll have people that don't join for the cause but because something in the movement aligns with them, we should allow those people to use the software without making this a purity thing, at the end of the day desktop Linux needs users, not zealots, first and foremost.

The fact that people can come in and put up with Linux in spite of not being here for the cause should be celebrated.
