So, it IS a Cummins distr^W car with other car parts that's not made by Cummins? Despite the big blue "Ford" everywhere on the car and in the documentation?
Another litmus test I often amused by is how when where is a report of a bazillion of Windows infections (especially those when a user should explicitly run the payload, not just a drive-by) then it's Windows problem, but when there is a report of bazillion of infected Android phones and tablets then of course it's not Linux and therefore it shouldn't be chalked up in any "Amount of infected computers per OS" graphs, lol.
> So, it IS a Linux distribution
Humans tends to omit unnecessary repetition and overall tends to shorten things when it's fits their current situation.
But that doesn't make "an operating system distribution based on Linux kernel with system instrumentation and userspace common to other popular operating systems based on Linux kernel" equal to "Linux distribution" or "Linux".
