I don't know whether or not PureOS is libre, but I just want to suggest that anyone investigating this question be extra thorough. Purism has a history of making promises they couldn't keep (namely the promise of making the "librem" laptop respect your freedom, something which is literally impossible) and using deceptive marketing, such as this absurd graph:
https://archive.is/HBDm3 Perhaps I'm being paranoid, but I can't help but wonder why Purism felt the need to fork Trisquel. The only possible reasons I can think of are to add proprietary drivers, or as yet another deceptive marketing gimmick. And I couldn't help but notice one of the Linux Action Show people mentioning that the "librem" laptop's touchpad didn't work as well on any other distro he tried, including the then-latest Ubuntu, as it did on PureOS. I can't imagine why this would be the case if PureOS is libre. -- Julie
