Why do programming language (open) standards cost money? [closed]

Question

Isn't it counter-productive to ask for 384 Swiss franks for C11 or 352 Swiss franks for C++11, if the aim is to make the standards widely adopted?

Please note, I'm not ranting at all, and I'm not against paying; I would like to understand the rationale behind setting the prices as such, especially knowing that ISO is network of national standard institutes (i.e. funded by governments). And I also doubt that these prices would generate enough income to fund an organization like that, so there must be another reason.
