Providing infinite support for all software would greatly increase the cost. I don't think that is actually what users want. I think the way that Microsoft is managing this is actually a pretty fair system. 1. Included with the base purchase price you get a predefined period of support. 2. You can pay more to get longer support. This way users that value longer product lifetime are the ones paying the cost, not the ones who are happy to update to the new version every few years. Whether or not the specific prices are fair is a different (and much more complex issue). But I think the model makes sense.
