Lemmings have a reputation for mindless groupthink, due to the unfortunate myth that lemmings are prone to jumping off cliffs.

I imagine a world beyond proprietary software, and GNU/Linux is the most promising implementation of that.
I don't agree with reducing software-freedom to an issue of mere privacy-friendliness. I'm willing to be realistic about the security shortcomings of Libre software but not if the alternative is locked down silos and walled gardens.
