That sounds like a good advice against using those desktop OSs, not like an advice to have it on mobile too I didn't know MacOS did this, but I'll keep my distance, thanks.

It's worth mentioning that the Xposed framework requires root which is a no-go on devices like BlackBerry Priv (mentioned in the other, HW-focused thread) and unfortunately on some other phones (Samsung) as well, unless you want to rely on a random binary from the internet (SuperSU) with no available source code. I thought most/all Android phones were safely rootable, but I learned the hard way it's not the case. So it's probably good having transparent root as one of the conditions for a purchase.
