To surface some important info from the link: IETF standards votes are open to anyone on the mailing list, and a number of NSA workers are voting for the first time on any of these standards in favor of weakening one particular one.

Given that it's effectively open to the public, the creator of the linked site is urging people to sign up and vote in opposition.

It's a quick read and all the relevant links are there for involving yourself if you wish.
