It's not about open standards, just standards

If I remember correctly 1/3 of the funding of the ISO was to come from the sale of copies of standards. This clearly implies that copies of the standards must be fairly expensive because not many people are likely to buy a copy of a standard and those that do are unlikely to buy many copies. In at least some cases, in particular the SAS and scsi enclsure services standards, the draft standards are free and include the information only otherwise available by buying a copy of the standard. I can ask a SCSI device about its health and serial numbers (more than 10 would not be uncommon for a real SCSI device), read and write data, format it, etc just by reading the free draft standard.
