All the songs I have copied to iTunes get uploaded, but if you have the lossless versions they get converted to normal quality on other devices, or if you remove the local original copy.
Music doesn’t support flac, though, you have to convert them to alac first.
I also use a Mac, I don’t know if it’s different on windows
I’m sure they understand the problems, and they understand that solving them would eat into their profits
