(I’m the founder of this initiative)
While there is a technical issue here, there is also a legal issue and a PR issue.
Government institutions have a duty of care and a duty to help to private individuals. Since they are apparently working _against_ people in this case, they are probably in breach of the law.

I strongly suggest that you file a formal complaint against the government agency. This is easy to do and you can do it here. https://www.jo.se/sv/JO-anmalan/
When you have filed the complaint: MAKE IT PUBLIC (hacker news follow up story, twitter, linkedin, etc). This is because there is a political dimension to this issue and if there is anything politicians care about, it's jobs (their own).
Good luck and keep us updated! I'm sure lots of people will be happy to spread a copy of the complaint around.
We just recently filed an appeal regarding getting access to the API documentation.
We have gotten a lot of PR in Sweden from the major news papers and tech press. So I think the pressure is building but if it is one thing Swedes are worried about is the appearance internationally. So help us getting this story to Wired, TechCrunch etc - that will make them crazy. We still live on the front page of Newsweek from 2000 - the capital of Internet. That might be true for the tech scene but definitely not the public sector.
We would rather concentrate our limited time and resources on making the product better instead of this crap but we have an amazing community that are helping us with both legal advice, artwork, communication, UX etc so we will continue the fight and will keep you updated here in Hacker News.
Thanks for all support so far!
Also keep in mind that the legal options and PR options are tightly coupled. Regardless of the outcome of any legal option (e.g. "JO anmälan"), the PR generated around it may itself lead to a change if it gets enough attention (e.g., Anna König Jerlmyr seems to be in charge of Stockholm municipality at the moment). Make it easy for them to get good PR and make it clear the other option is to get bad PR.
These questions are larger than this project. This is about how the government itself builds API:s. That's big.
