The problem is that most of the licensing solutions (Google, Amazon, Galaxy App Store) don't support a concept of a trial. You are either a paid customer or you are not. So I would have to implement a lot of logic to determine how long it has been since the user downloaded the app to see if they need to buy it. The problem with this model is the user could just uninstall and reinstall, and I would have no way of stopping them from using all of the functionality without paying. So I'm just trying to protect myself. Additionally, if I had the kind of users of the free version leaving reviews for the paid version, that would just hurt the ratings on that version. At least this way it kind of filters out the people that really don't seem to have any intention of using the app anyways.
