Mostly, yes. But Richard Stallman takes FOSS to a whole new level. What you thought was FOSS, he could find a way to say otherwise.
Licensing, Code, Drivers and everything has to be FOSS friendly for RIchard Stallman, of which Linux has a few areas where that isn't 100%. Even if it means losing core functionality of a machine without said code. And all these are increasing in numbers in the recent years, it'll only be a matter of time before Stallman says good bye to Linux because of it.
