No. This is a result of a market failure caused by monopoly power. Regulators must make sure market capitalism works.

I'm not sure what is the basis for your question but using market definition where Google Play and Apple Store are in the same market is not correct (market definition is essential part of any monopoly regulation).

Markets are defined by choice of practice, not by choice in principle.

My question is: what is the basis for asserting that this market failure is due to monopoly power? Is your argument that their excessive profits from the services provided result from anti-competitive behavior? If so, what specific anti-competitive behavior are you referring to?

The specific cited anti-competitive behaviors (from DOJ and EU Commission is) are related to violating anti-steering provisions (companies forbidden for directing towards other payments methods), tying and bundling (in-app purchase requirements), self-preferencing (obvious), "tap-to-pay" monopoly, and blocking third party app-stores.
