What does this have to do with Apple's "walled garden"?

They are able to charge 30% of app revenue because they can. They are a for profit company.

Amazon Fire did not do that because nobody uses it. Now that it has some traction, lo and behold, they want their cut as well.

If anything, Roku is the direct competitor (low cost streaming stick) and they take 30% ad revenue. But Apple gets the blame. lol.
