All countries with a working democracy would class Apple as a monopoly as it has significant market power, enough to distort prices.
The market is mobile devices.
Now suppose you have an iPhone and want to download an app, or want to distribute your app to customers many of which have an iPhone. What substitute for Apple's store is available to do that?
Apple can change their rules and it materially impacts the market.
If it helps, think if Windows apps had a 5% Microsoft tax and had to be approved by Apple.
When they were found in the US to have a monopoly, they had around 95% of personal computer operating system share. Apple isn’t even close.
For iPhone apps Apple is way behind with about 0.005% of the total 2.17 million iPhone apps.
I.e. the monopoly question is: if apple takes X% for each app in this market, and a competitor can't take less, then it's a monopoly.
1) find some space on the shelf and your stock room to put my stuff! 2) I don’t have a store with shelves or visiting customers, but you will sell this for me at 0% profit!
You’re paying for sales access to millions of devices with frictionless checkout.
And you want to… make it harder to check out? Because you think you’re entitled sell things to their user base?
No one wants to go to your website. You’re crazy.
However, in this scenario every neighbourhood only has 2 STORES - and each CUSTOMER only shops at one of these STORES.
Then, if you made HATS, the only way to sell HATS is to get them on the shelves of both those stores.

This is Australia: two major supermarkets - so the only way to sell a lot of your product is to submit to the terms of Coles or Woolworths.
It's not about the market for apps, or the market for smartphones. Those markets are comparable to any market.
This is about the market for apps ON the apple ecosystem. And the problem that is being solved is: Apple can't have a monopoly on that market, such that they can (for example) charge a commission for every sale.
Basically: we can't allow a company to be so successful that their STORE becomes a MARKET.
