gmaxwell (Gregory Maxwell) is also a core dev and has expressed his concerns about the situation on Reddit: http://www.reddit.com/r/Bitcoin/comments/27lotn/people_dont_realize_how_serious_a_50_attack_is/ci27dpy
He's saying that a pool with 30% is just as bad as a pool with 51%, so according to him the current situation is not any different than before as there have always been pools with around 30% of the network.
Wait, all this time they are concerned the whole bitcoin thing is broken, but they picked this date to all of a sudden spread their concerns? What a bunch of assholes imo, sell their coins and suddenly express their concerns.
