Factory Shop Manual on DVD

I am looking for the 2002 factory shop manual on DVD. I see them on sale on Ebay and was hoping some had a torrent link.

Someone here in selling them. I tried looking at some torrent sites (not even sure if that is legal) and I couldn't find any.

I did find a online share to download the files from (4.5gig). Too bad I already had purchased a DVD.

Also found GM Parts manual 93-02 (128gb)

Can you verify that all of these are legal sites, and are not violating copyright laws?
