Good catch. But the SHA hash is salted per backup destination though. So you can't figure out the content from the hash alone.
EDIT: I should make note of that on the docs page really. It currently gives the impression that I'm just straight up calculating the sha of the content.
Obviously this is needed to make block level deduplication possible, but it also means that for this "end to end encrypted" product someone can still tell whether or not you own a given file. This is probably fine for most people but worth calling out.
