This is still a pull & not a push. No one, not even the almighty House of Bill, can start a connection to systems behind a firewall & using NAT. The client system has to initiate a connection to the mother ship.
That said, the problem is that it's a push against our will. There have been several times over the years when Windows Update has required an updated version to run; I see no reason why this needed to be treated differently. MS had other options but chose to do something that's being perceived as invasive. Shame on them.
