It is. Software doesn't rust. My old copy of Office 2000 still works perfectly fine -- with Wine. Windows 2000 and Office 2000 were the last versions I bought. When M$ switched to activation-based "copy protection", I moved on to Linux and never looked back.
But the thing is: You pay for something, and it works. Then, just 11 years after the sale, the product suddenly stops working, just because someone said so, even though it's still in perfect condition. That's a nope from me. Imagine you buy new shoes, and after a while you suddenly can't put them on anymore. Or an oven doesn't work anymore after just 11 years. With M$ stuff it seems to have become a new "normal"...
