The FTC was warned at the time that they were flouting required procedures and that their rule would therefore not survive legal scrutiny. Lo and behold it did not.
A then-commissioner who is now the head of the FTC.
That commissioner also hated the fact that consumers were going to stop being robbed by big corps.
I find it unproductive to assign emotion to such blatant corruption. I'd rather frame it as "That comissioner sees it to be in his personal best interest to not stop consumers being robbed by big corps."
