A lot of people must have bet the over and didn't think the Steelers would cover...
Tells me that there are alot more fans in this country than just Steelers fans who were watching the game objectively and saw quite a few bad calls. Coupled with about 3 to 5% biased Seahawk fans that feel strongly that they were robbed, and you get quite a few complaints. Thusly, it appears that the other 5% of the fans in the country who happen to have a strong Steeler bias somehow, didn't notice the lousy officiating. Funny how that happens, huh?
