That answer was technically correct. Without basic hardware knowledge, you would not know why. You should have also known about extensions that makes possible multiple FAT32 partitions.Why would that make a difference when your (flawed) argument is that the file system is robust enough to recover from write interruptions?
You immediately denied/ignored what you never learned. Every disk drive (even before PCs existed) learns about power off after AC power cuts off. You should have known that before casting 'flawed' insults. A USB stick has no such hardware protection feature. If you did hardware, then you knew why. NTFS is designed in conjunction with disk hardware protection as part of a unified solution. A typical USB sticks does not have hardware to protect data from sudden power loss. You should have known that.
Sudden power loss does not corrupt data on modern filesystems. But a destructive event, that once occurred on obsolete filessystems, survives in parables - 20 years later.
