At least in Germany all cheap USB sticks sold to average consumers in stores are still FAT32. I highly doubt they format different fs for different countries, the printing on the packaging indicates they're all sold EU-wide. FAT32 is still very dominant & I wonder why Microsoft & Apple don't push the vendors to use exFAT. Users unaware of filesystems won't need their stick being recognized by the UEFI, but they will have files > 4GB.
