> Apple doesn't have a monopoly on software distribution.
This is just literally wrong, by-definition.
You can claim that Apple's monopoly isn't illegal or harmful, but the monopoly itself is self-evident. You cannot distribute software without Apple; their system is designed with monopolistic capability.
> The only people who would benefit from forcing Apple to allow alternative stores are the unscrupulous middlemen who would run them.
Source? You're inventing hypothetical claims to support your rhetoric.
