How this is checked. Keys, devices, networks and incidents are checked by hand against the maker’s own documentation and published post-mortems, each with its date. Code activity is read daily from the wallet’s public GitHub repository (commits by people, not bots, over 90 days; the latest release). Ratings come from Apple’s public App Store lookup. Nothing here is paid for, and nothing decides the order.
