This aggressive dilution of the monetary value of software is what I think contributed the most to the loss of gameplay quality and the near-criminal, constantly-nagging-for-payments-and-ad-views behavior of app publishers today.
Mobile software should have been sold more like shareware used to be sold - free demos with limited functionality -$5 onwards for complete versions.
But now it is too late, the dilution of value of mobile software has only benefited app store owners.
