ISPs' willingness to take action

Brian Bruns asserts that there are lots of home users
connecting to their office Exchange servers without VPNs,
and that therefore blocking the Microsoft ports was bad.
While I agree with his point that you shouldn't do it
without documenting what you are or are not blocking,
I'm really surprised to hear the assertion that people are
leaving unfirewalled Exchange servers out on the net.
Is this actually common?    /shudders...
