The problem here is the smartphone ecosystem. If there were merely an "app standard" which I could run even if I did not have a Google or Apple device, that would be fine. But, requiring that I give at least some information to Apple, or even more information to Google in order to use a government service is what I take issue with.

The bigger problem is that this issue is almost entirely artificial. Most apps are merely glorified web pages. Functionally, they could (in most cases) just be websites and function exactly as well.
