Because it's FAT.

If what you want is all the files on the same group, you may use mount
options to set that.

For example:

mount -o group=mygroup /dev/sdx1 /mnt/myusb

But if you want commands to change groups or permissions, you should
reformat the filesystem. If you need Windows interoperability, you
might want to try NTFS, I don't know if it works, but if you have the
device, the machines and the time for it, you might as well test it.
