User testimonials: where is `apkeep` used?

I know of a few places where `apkeep` is used, such as F-Droid and Exodus Privacy infrastructure, as well as providing a tool helping in various research efforts.  I would love to have more user testimonials to measure impact and showcase the project.

Please either comment below or reach out to me with your stories of how you're using the tool! bill@eff.org
