I don’t know about CERN, but I do suspect that MIT and it’s MIT Lincoln Labs (as an FFRDC) would not jeopardize it’s long standing and lucrative position in government grants, contracts and protected budgetary status in abetting the development of an encrypted email service that the NSA could not decode. It is just not gonna happen.
Well CERN is totally funded by governments so it is owned by them even more than MIT.
