I think it bothers OP less that they take a 15% tax than the fact that google provides terrible support for their own play store. If they would take that tax and provide good feedback and speedy version reviews, nobody would ever complain - it is expected to pay something since the play store doesn't run on good thoughts and prayers. But because they're a monopoly (or a duopoly if you count apple, which is a different platform altogether) they can afford to act this way.
