Hackers acting as if they're doing a public service by bringing down a free publicly accessible tool is a new level of assbackwardness.
If the goal really was to force IA to increase their security, they would've tried to consult with them. This is more about notoriety and chaos and the hackers have no moral ground to stand on.
I actually was fortunate enough to visit the Sistine Chapel this summer, and although when you take a close look at images online of the paintings, it's clear they aren't "realism", when you see the paintings in person they look very real. I was especially struck by how real Jonah looked, as if he was just hanging out, sitting on a ledge near the ceiling. Very cool experience.
