I just love it
So the IE9 "do not trace" function has a hole that depends on TPL creators to not be abused.
Obviously, it's a "feature", because anything Microsoft does that the public does not like is never a bug and there's always important "public" (i.e. big-spending customer) support to justify it.
I'm sure that, if a general outcry against said "feature" is raised, Ballmer will certainly trot out the line that the "customers" wanted it. And he will be right, of course, albeit not mentioning that the "customers" he considers are not the teeming millions of anonymous users, but the select few business partners with deep pockets that made the requirement list (and screw the rest of us).
