You pay them cash to stop them from doing something to you... Doesn’t this sound a bit like extortion... protection rackets? Where’s Rico when you need him...
To be fair, the money they get from companies to put this crap on PC's is what subsidizes the deals they offer on new systems.
I myself always formatted any new system I got with a fresh version of Windows. Before I switched to Linux that is. (That's right, I'm one the usual crowd that shows up and says the same thing in every computer thread)
