>It's not Microsoft's fault that people depend on Windows XP.
When XP was released, Microsoft was unarguably a monopoly. Monopolistic businesses have responsibilities that other, non-monopolistic businesses don't. The law is vague, but the FTC could reasonably force Microsoft to continue to patch security problems in windows XP forever. After all, the defects to which the support period refers existed within that support period, regardless of when they were proven to exist.
