Re: The Management.
Not quite.
As has been pointed out, most of the standardisation work is done by experts who are paid by their organisation (often from a standards lobbying budget) but are not paid by ISO. The same applies, incidentally, for the sister organisations IEC and ITU as well as the ISO/IEC JTC1 where a lot of the IT-related standards have their home (AI is subcommittee 42 ... someone read their Hitchhiker's Guide, apparently, but I digress.)
The budgets of ISO, IEC and ITU are used for administration purposes. A lot of admin work is involved in managing approval processes among the national bodies, creating new committees, managing workspaces etc. I am sure there is waste, just like in any bureaucratic organisation, but the comparison with Nominet is rather unfair.
The argument for making standards freely available is solid. This means that ISO, IEC and ITU budgets will need to be funded solely by national body contributions, which in turn means that national bodies need to raise additional income (often this is a government grant). Maybe it is indeed time to do just that.
