Yikes! That's not nice!
One point for scraping grounds...
Regarding the "French/Schuko in ungrounded socket" issue, after all it's only turning a Class I appliance into a class 0 appliance - and after all for example my lamp definitely _is_ a Class 0 device... still, I'd never plug grounded electronics stuff (like computers) into an ungrounded receptacle for fear of electrostatic damage. On the other hand... my first computers accidentally have been plugged into ungrounded outlets yor years - after some plumber removed the ground connection to the water pipe in the bathroom we didn't have a ground anywhere and never knew until we relocated the meter! (Who would have thought the ingenious sparky in 1978 didn't see any necessity to include a ground wire with the new feeder???)
