I'm going to go out on a limb and make an assumption that the point of the relevant portion of the EU privacy directives is that information about an individual should not be disclosed without that individual's consent. (At least that's what I gather from some limited reading.) If you can get through the 72 "whereas" clauses,
this page is probably a good place to start. Article 8 deals with some special circumstances that apply to the Church and includes the phrase "data are not disclosed to a third party without the consent of the data subjects."
There has likely been a lot of research and effort expended by the Church to determine what is allowed, what isn't, and what is required. The legal requirements will be reflected in the way that the software works. The stake clerk doesn't have the legal right to make an opt-in decision for everyone in the stake, so the system isn't going to allow that. Allowing it could result in unpleasant repercussions for the Church and possibly for the individual involved.
Although it might create inconvenience or additional expense for the stake, we believe in obeying, honoring, and sustaining the law, even when we don't like it or it is inconvenient.
