You get to write your own drivers from scratch, so you know for sure no one is spying on you 👍.

Linux took off because, one, it wasn’t backed up by an institution or a company, just one guy doing weird stuff with his computer, and two, because of the license. People don’t like investing time in something that others might use for free in their commercial products. And not only that, but they’re not bound by law to release the source for that. And this is the reasson why every printer out there runs a BSD variant, not Linux.
