Having tried to explain to paper-pushers why I suggest they release some data they have to the public, it always came down to how much effort and therefore time==money it will take. Throwing some existing spreadsheets onto a download site takes only a few hours (yes, hours, that's how big buerocracy moves), after which they can move on with their actual work.

Any kind of reshaping of the data needs to be done by a data analyst and those are usually not readily available to work on projects that ultimately give no value to the organisation itself. Creating APIs takes developer time and server hosting/maintenance costs. Writing documentation takes almost as long as developing and if you now also want to provide it in multiple languages...

Accessibility is awesome and should be a hard requirement in any essential system, but anything that's entirely non-essential, few people care about and os done pretty much out of kindness and nothing else (has no ROI) should not be expected to be perfect or even good. There was a story some time ago about some lectures being provided online for free that later had to be taken down because they didn't have captions for the visually impaired. Don't let open-ish data go the same way.
