If you sell through the Apple App Store, Apple charges 30%. This is the industry standard when you sell through storefronts PlayStation, Steam, Xbox, etc. If they sell through their website then Apple doesn't charge any fees.

They knew well ahead that Apple would take a 30% cut so I don't understand why some commenters are saying about why this is a "problem."

I'd prefer the money goes to the Document Foundation, who already need to pay to use the app store. It's not a major issue, but it's a downside to the decision in my eyes.

Because they would make the same comment on the playstation, steam, xbox etc. store? I am not sure what you think the "problem" is supposed to be instead or why it needs quotation marks.
