You updated your post to add this after I said I agree:
> Distributing software without the permission of the author is the definition of software piracy. This is literally software piracy.
It's disagreeable that you'd make such a drastic change under my feet.
So to update my previous stance, I there may be some technical ground but I think users have a right too, to archival, to exploration. Leaving the software with all copy protection intact & in an unusable state for a user is pretty obviously difference than the hard fast clear case you make this out to be. This is pretty obviously different. Technically it's probably not up to snuff but the law is probably not competent in technics & needs to reel itself in to maintain legitemacy.
There is significant public interest in being able to look at & understand & see our past. Microsoft doesnt wish to be a part of that past but I dont believe it grants them the right to make the world forget & become ignorant.
