Oh, I got one of my own: The notion that Linux is for enthusiasts that spend most of the time tweaking their computer, and therefore Linux can’t be used by an end user who just want to get things done.
Close to this is the classic adage: “Linux is only free if you don’t value your time” which is an extension that assumes that extensive tweaking is necessary to get to work, not an option available to the power user.
(But they still complain when Microsoft fucks over their workflow on every update. It is a double standard because Microsoft is “a brand”, so yes, I will say it is a Linux-specific bias.)
The borrow checker checks literally that you don’t take foreign things, so there is that.
