What you say is for the most part true but there are a lot of developers out there on the ios platform too who have put that same effort into making apps but they choose to make them free. Based on this I just thought to myself what if the moderation concept was applied to the app market.
It's about motivation mostly and an effort to try and improve the quality of the apps out there. Google needs to address this issue at some point. Apple addressed the issue of fart apps didn't they. Higher quality apps being developed as Android only means a lot to the folks at Google. It's excellent pr and great for marketing the platform. Even with the featured app program there currently I don't see improvement. I see apps ported from iPhone hitting the top quite often actually.
So yea. I got what you said. But if Google wants to improve the app quality they need to be proactive about it. Very! The question was how to be proactive without killing the openess
Sidenote- as far as paid apps go Google devs anyway have a different mindset which focuses on the freemium business model. So they wouldnt mind working to get into the 'Google approved' list since that would just increase chances of people purchasing their full software
Thanks for commenting btw. Really had to think on that
