Everything I EVER wanted to know about "the why" sir, thank you very much for taking the time to go into such detail!!

Add to that that SD cards are designed to be storage ... not dynamic memory. The constant read/write to flash memory will accelerate it's useful life and then one day, you go to use your super selfie stick app and BOOM not only is the app gone but EVERYTHING on your SD card. Couple with that the low quality SD cards and counterfeits out there and it's an accident waiting to happen ... like juggling flaming chainsaws blindfolded.

Of course everyone always religiously backs up their devices. That's why we almost never see threads about retrieving lost files.
