Then it deserves what it gets.  Market forces are intended to penalize
companies that do stupid things and if we interfere in those market
forces, it will only encourage more stupid things.

Or you could look at it this way: RCVD_ILLEGAL_IP was a really good
spam indicator until Microsoft messed up, so by using those IPs Microsoft
is helping spammers by forcing spam-fighters to reduce or abandon a
pretty good rule.  Should that sort of behavior be rewarded?
