I think a lot of what Apple has added to their App Store in the name of security is really just to get developers to move to recurring revenue models, which in turns makes Apple a lot more money. An old app that hasn't been updated in a couple years isn't inherently dangerous, but if Apple can convince users that it is, then devs will have to rethink how they do business. It's a shame to watch Google copy this move too on the Play Store.
