Toyota doesn't have to keep paying for your maintenance, whereas MS does keep having to pay for their time to develop patches for XP.
A better :caranalogy: would be whether, as emissions standards come in, you lose the ability to drive your old car unless you upgrade it. Except even then, Toyota doesn't pay for the new ECU instead of your carburetor, but you expect MS to keep maintaining an outdated seucrity model.
Moreover, if you don't upgrade it you DO get forced off the roads, namely by legislation prohibiting its registration.
