The first link is very interesting. The author talks about the alert in terms of a dark pattern, but the notification directly lies to the user stating "cannot be opened." In fact, the app can be opened by simply command-clicking and selecting open. However Apple lies to users in an effort to prevent them from using these applications. Sounds like a possible tortuous interference claim, or possibly fraud. Surely this "warning" serves to prevent users from using apps where Apple doesn't get a cut, and cases them to use apps that Apple does profit from.
