Interestingly, ISO standard documents are sold for a non-insignificant price and DRMed, while people writing them are volunteers and/or paid by their employers to participate in standardization committees. A company willing to build equipment for an industry running on ISO/IEC communication protocols (like electric power distribution) may have to pay thousands for relevant standards, or rely on someone's interpretation of said standards to implement the protocol before they even begin, not considering certification costs.
