So, err, you're saying that all your users are being encouraged to, err, upgrade.
Just not to a Microsoft product.
So I think the comment ("everyone... will upgrade eventually") is entirely accurate, no?
Mind you, if you think Microsoft is an abusive relationship, what the hell is Apple? The only truly honest assessment I've seen notes that the principle difference between Microsoft and Apple is that Apple is *better* at the process of abusing you. You're still abused.
