This makes me think: What is the basis of trusting any organization or person not to have their own agenda, possibly contrary to the group’s ostensible agenda?
The basis is this: We have a tacit assumption that all participants have realized that better standards (and strong crypto, more secure systems) will lead to the betterment of all. This is the default assumption.
However, now that the U.S. government, and the NSA and its collaborators in particular, have been shown to explicitly not have this goal – in fact, their goal has been to strive for less secure systems and more difficult standards – what should be done? The logical thing to do is to exclude any person or organization revealed to have an agenda explicitly contrary to the group.
The same argument could be made (and has been made many times in the past) for Microsoft to be excluded from any and all standardization committees like ISO, IEEE, IETF, etc. for the same reason – their repeated practice of Embrace, Extend & Extinguish among other things shows them to have an agenda contrary to the group, and their participation would therefore be a detriment, not an asset.
