I have an iPhone, and a mac (two actually,) and an AppleTV, and an Apple Watch. There are a pair of beats headphones sitting next to me on the coffee table.

Somehow, I still manage to write free software that I care about, release it for free, and contribute to other FOSS projects. Caring about free software doesn't mean I have to use ONLY free software.

That's pretty much the opposite of reality.
