The FTC reached a settlement with Google this year for a $22 mil fine because Google violated a previous consent order over Buzz.
Yahoo is not under an existing consent order with the FTC. For the most part, the FTC does not get fines unless a company violates an existing consent order.
Furthermore, Google didn't get fined because it circumvented Safari's privacy settings, but rather, because it lied about the extent to which users could opt out of tracking.
I've not seen anything that suggests that Yahoo is lying about the extent to which they will respect or ignore the DNT header.
The FTC's deception powers aren't going to be of much use against Yahoo here.
