What should they 'know'? If they can use it for their purposes then it is, per definition, usable. It's like saying that 'most cars are unusable for getting around'.
As somebody born in the USSR I can easily imagine how cars will be barely usable for getting around, and people who bother with cars will be called 'car enthusiasts' instead of 'people'.
We're there with Windows 10. We were better off with Windows XP and arguably we're much better with Android.
They should know that not all cars break down two times a month on average and that black smoke is definitively not a feature.
