I agree with the article 100% - laws need to be freely accessible to everyone. One particular standard which I hope they publish in the future is the HIPAA standard(http://store.x12.org/store/healthcare-5010-original-guides). It's pretty outrageous that to implement any form of electronic interfacing with Medicare, a government insurer, you have to pay $2500. And it's not just a one time cost - you have to keep buying them every couple of years to keep track of new additions / errata.
You don't have to keep buying the HIPAA standard from them. It is freely available by FOIA request.
What you are buying is an edited guide that includes the latest version of the standards compiled into a single document, rather than a collection of separate documents and their amendments that you must piece together yourself into a single coherent document.
