Possibly the difference is that a govt department applying laws passed by an elected parliament accessed information collected under legal means ... rather than a company that collected your data for one purpose the turning around and allowing another group of people to access your data for their financial benefit despite their being federal privacy laws that specifically prevent a company from legally doing that exact thing.
and to be clear I have NEVER in 25 years of flying ultralights, Microlight’s it GA not paid a landing fee. BUT I absolutely do not want my personal data being made available to groups just because it is simple and it I might get a group to support the RAAus.
