I wonder if Apple should review, warn the developer, and drop, if necessary, low-rated software. Obviously, this requires manual review (people gaming their competitors, a single updates has a regression, PEBCAK, etc).

I think it would be easier if they just removed apps that clearly break the rules, like this one. I mean, there's no real reason an app would redirect support to an unrelated third party who didn't want to receive it, so why not just remove apps that do this? Same with any more apps that pretend to be from companies that actually played no role in development.

Seems like a good idea would be to, upon submission of an app, for Apple to send an e-mail to the support address to confirm it?

I dunno, maybe they already do that, but it seems like any credentials entered should be validated somehow.
