Equally, pretty much no iPhone user (outside of tech circles) cares about the App Store monopoly for iPhone. The policy is well known, and hasn't changed in 15 years.
Indeed many (not all) tech folk who complain about the App Store still went out and bought an iPhone.
The raw truth is that the market did decide. And no we don't need regulation. Apple and Google have different enough policies for there to be choice. In some countries Android has dominant market share.
