Devil's Advocate time. Would the result of that be better or worse quality public standards?
(I don't actually know what I think off the cuff - but it's the obvious follow on question to your statement and I don't think your statement can stand on it's own without a well argued counter)
It's a fine question. I think the onus is on public regulatory bodies responsible for the standards; if they aren't able to pay for the work to be published as an open standard, it wasn't worth the cost.
Standards also benefit the industry as a whole, and it's generally in the interests of the companies involves to participate in the standardisation process anyway. Charging for the description of them is just a cherry on top (compared to e.g. licensing any relevant patents), I don't believe it's at all required to incentivize a standardization process.
(this is of course looking at interoperation standards - regulatory bodies are going to be more concerned with e.g. safety standards)
