One common workaround is to go to "the Estonian site" which offers the same, English version of standards for a much lower price [2]. Being a bit cynical, I would say that Estonia prioritises open information much more highly than.. other developed countries. I created a price comparison on my website [3].
But: The core problem of standards being openly available is still not solved. Why is this not possible? For me, standards are very comparable to the law: A large number of people should comply with it. For that, they must be openly available to everyone. Everything else doesn't make sense. Is that unreasonable?
