Cam, your mistake is the possession of an opinion critical of the "FiA" - otherwise known as the FIA to those who don't automatically kneel before an altar of "power." The "FiA" doesn't make mistakes; it merely presides over them.
That said, I'm afraid I have to - *gulp* - agree with ol' Blue here. When it comes to F1, the FIA is little more than a rubber stamp entity whose only role is to lend a facade of legitimacy to the circus. If it had any real power, the regulations would look a whole lot different. (They'd probably be enforceable, too.)
I blame the teams and Pirelli for the current crop of "tires." The teams like having an easy scapegoat, and Pirelli likely couldn't do much better anyway.
