@Natanox @fuchsiii just like #Valve does on #Steam:

You don't own those games but merely get a perpetual license to access these games...

Only on actual licenses you have some sort of "ownership" as per #UseSoft - case where the original owner can't ban or restrict the resale of your license and adjacent media...

Which is why #Adobe canceled #OneTimePurchase licenses: Because they got forced by a court to allow #UsedSoftware #License brokers to sell used copies of #CS6...
