I don't see the problem here. Information, just like everything else, can be used as a weapon. Some information needs to be kept out of the hands of people who aren't responsible enough to use it. This is standard practice with other things.

The knee-jerk reactions against "censorship" in this case doesn't make sense. From what I've gathered from other articles about this research is that it basically lays out a procedure to take bird flu and turn it into a potential pandemic-causing virus. And we're not talking highly controlled lab experiments here, this is something that a rag-tag group could do in a regular building (again, from what I've inferred).

The potential downside to having this information freely available far outweighs the benefits. Any legitimate research group will surely be able to get their hands on the information.
