Apple has had the same problem for years. …
I was about to say the same thing, I used to work in an electronic store and I sold more chargers for MacBooks than for any other laptop, exactly for this reason.
The Apple charger cable is hideously thin and always fails right after the strain relief boot.
While these Apple and MS chargers can do with improvements, I would though personal observation, put these failures down to operator error more than design fault. Put it this way, I have some friends who I wouldn't even lend even a MIL-STD-810G laptop to.
