problem remains that there is no consistent design distro to distro

You might have had a point if you wrote that back in the days before phone UIs and Windows versions and websites all completely redesigning their UIs every 5 minutes but this is clearly nonsense at this point.

Can you imagine your grandparents trying to use Linux and then looking stuff up on their own and then doing something wrong because they don’t know what distro they’re on? Nightmare.

No, actually the actual nightmare is them using Windows and asking me about it on the phone and me having to talk them through mouse clicks in an unfamiliar GUI instead of just telling them which command to enter in the terminal like I would on a sane OS like Linux.
