IMO we do need to change our anti-trust definition to get rid of the requirement to show consumer harm and decide that concentration, in and of itself, is against the public interest. It's hard to demonstrate consumer harm when you don't know which technologies didn't get started because of high entry costs, or because high app store gate-keeping fees. We should also discourage obtaining a monopoly as the end goal of a business. This is not to say that we should make the notion of an appstore illegal, as there is consumer benefit in a curated app store, but something like limiting fees that can be charged to a reasonable association to fees recoverable from the expense of maintain the app store infrastructure and app-review infrastructure seems like a reasonable requirement. E.g. regulate natural monopolies that cannot be broken up like utilities.
