Actually, this might be a reason Gates got out of it. Gates is against piracy, but he's also against stupid moves in the company. It could be he's been against a lot of this "take over the machine" idea from MS...and with him getting out of the business to be with his wife...well...it lets those who are felons truly start taking the book.
I've had problems this past year with XP things occurring. That's WITH a LEGIT copy of WinXP...it had problems reauthorizing after I upgraded a computer. Had to even go contact tech support (which was a pain in and of itself even), and even then, it wasn't a walk in the park.
If they do initiate a kill switch, it might have nothing to do with Gates...and a LOT to do with others who are behind this push.
I hope if they do implement it it DOES damage Windows and MS's reputation AND SALES so badly that they change their entire shove of trying to shove authentication and all this hijacking of one's computer and abandon that approach...but are still in business so that we have continuity and backwards compatibility in Windows OS's.
