Allowing developers to pay for promoted placement is a terrible idea for Google Play's users, for app developers and for Google. Google Play users will now see more exploitative apps that are visible in search results not because they have earned high ratings from users or have a low uninstall rate, but because they are able to extract more money from each user to pay for their placement. App developers with quality products -- especially those with small development studios like my own -- will be put at a further disadvantage from the likes of King.com, Supercell and Zynga, whose high ARPU can justify this sort of promotion. And while Google will initially be able to extract more cash from the app economy than the 30% it already does, by diluting the value of Google Play search results for their users and by incentivizing developers to make exploitative rather than quality products, mobile device owners will become more motivated to migrate to other app stores and possibly other platforms.

I wish that Google would concentrate on its core strength and develop a search system for apps that directs its users to what they will appreciate and enjoy rather than what will cost them the most money, and that would encourage developers to aim for quality rather than exploitation.
