Seems like more like an atempt to lower price a bit for me, as not many people are happy with satoshis' identity. However it did not have much impact it seems.
I doubt it was an attempt at lowering the price and more likely Craig trying to make money off of people trying to get an interview with him or other things that would benefit his financial situation.
I also don't think its people not liking his identity, but rather knowing when they see a con artist. There seems to be very, very few people that actually believe his supposed identity.
