> Apple has a monopoly on the iOS App Store

The courts have ruled that the iOS App Store is not a monopoly.

They haven't, in the level of generality you imply. The ruling was much narrower: that Apple doesn't have a monopoly in the market of "digital mobile gaming transactions".

Perhaps you aren’t aware that the meaning of legal terms is decided by courts.

The alternative is that you don’t know what monopoly means and you are just using it a general way to say you don’t like Apple.

The meaning of legal terms are decided by courts for their jurisdiction.

When I, as european, wrote monopolistic, then that definition can still hold, as the European definition of that term is not decided by US courts.

Are you the person I was replying to?

I started the comment chain with my comment to which you replied "Apple has never had a monopoly on anything"

Have you looked into their profit margins? Do you still claim they are 90%+?

For the store? Most definitely, considering I can see what costs I expense for self-hosting all the infrastructure I need, developing the software, etc compared to what they want for it. That’s almost 2 orders of magnitude difference.

As opposed to random posters on the Internet?

hmm, Nintendo, Sony, Sega and MS all have a monopoly on their stores. In fact, Target has a monopoly to their retail stores. You can't just sell your crap at Target because you want to. Also to probably lose 50% to the retailers.
