this is because they are wimps. just do it. just do what an mp3 does but like with whatever. i want to shrink my gigabytes of random crap down to arbitrary size and send them fast to my pals. it's all just numbers anyway, right? so long as most of the digits are sorta close i don't see the issue. lossy zip a text file? you can probably make out most of the words. lossy zip a .wav? there'll probably be some sounds in there. you can listen to those. lossy zip an .exe? it might not even crash right away. maybe it'll do something cool. you don't know.
i am not joking you can now compress your files as lossy JPEGs
