So buying cheap OEMs from ebay may be no different than pirating them?
those oem licenses are cheap because are meant to be sold to oem manufacturers on countries where the economy doesn't allow to buy more expensive licenses and the cost of the entire pc has to be a low as possible, but they end up selling them in internet, that covers the entire planet, not just those small markets
officially is not right, but microsoft is not saying no to activate them, so is not ideal, but is not illegal really, otherwise microsfot would not only not allow to activate those, they would disable those licenses activated years ago using the same technique, microsoft what wants or needs iseverybody moving from old versions of windows into windows 10, free, cheap or expensive
on some sites where you buy these licenses if they ever get revoked and you end without license, they guarantee buyer protection and you get your money back
what i don't like is when you get a license key from a volume license, those indeed get revoked, because those license are meant to be usedwith a activation server inside a company using a local domain server, thye buy 1000 license vut those 1000 can get revoked all at once, if they ever bought them, if they are stolen from a company, you will loose your license and will have to fight for your money back
