What’s wrong with free speech absolutism? When I was still working for the ministry of finance, they had a tendency to resist right to information requests, leading to those requests becoming broader and more work.
Luckily one of the highest civil servants shared my view. The first step I suggested, and the most difficult, was, how do I do my job that I can freely talk about it when having drinks with a friend? Eg., on an everyday basis I shouldn't be working in such a way that nobody except my boss is allowed to know what I'm doing. That's asking for trouble with respect to accountability.
Second, we changed the process, instead of resisting information requests, we started calling those who submitted them. "Hey, you're asking for a ton of information, I think we can all save time. If you tell me what you're trying to find out, I'll try to collect everything that's relevant to it and then if you still feel things are missing, just give me call, OK?" Handling time of information requests has been halved as a result. Whether the first point has made collecting information easier I don't know because it's hard to measure. Alas, that's only one ministry and the high level civil servant that thought it was important has left.
