That's a pretty broad root cause. The problem is coming up with a remedy that can't be worked around or doesn't distort the market in other ways. It will be interesting to see what happens in Europe if/when they force Apple to allow side-loading apps.

The EU redress strikes at the core of the issue -- if Apple and Google are prohibited from monopolizing app stores and/or payment processing on their respective platforms (including via incentives, tying products to exclusive use, etc.), then their mobile OS/hardware monopolies loose a lot of their power.

The bigger question to me is to what degree will the platform owners be restricted from monetizing apps on the platform. Requiring apps to be installable at no cost to the developer makes a big assumption that platform fees are 100% rent. Some of the fee surely is, but if enough people are able to circumvent fees, it seems likely to impact the dynamics of the platform, e.g. If supporting 3rd party apps become less profitable, why wouldn't Apple and Google shift focus/investments to first-part apps and features and allow public APIs to languish?
