We need new laws because existing ones don't account for the existence and importance of computing platforms. But the problem is very obvious. A 30% cut for something that is completely free on other computing platforms is evidence of excessive monopolistic power. This power is exercised by means of restricting what kind of software end users can run. It is not hard to imagine several reasonable ways to restrict that power depending on how far you want to go and what tradeoffs to take. The only seismic effects would be to owners of walled gardens mandated by device manufacturers, i.e. Apple, Google, Sony, etc. – exactly those who are currently abusing their market position.
