Where it all falls apart: Apple recently targeted 30% of Airbnb's (and ClassPass') virtual experiences revenue. These experiences do not make the app itself better (others were saying here these are done via Zoom). It's a transaction to set up people performing for others (not a purely digital good) in another app like Zoom. It doesn't really change/improve the Airbnb app. ... But Apple aims to treat it as an in-app-purchase...
Unlike with the Wordpress controversy, Apple has not backed down or apologized to ClassPass/Airbnb, demanding both still comply with the 30% rule by year's end.
As a user, are you buying ad placements on other people's news feeds? If so, I'd be very confused why you would continue to spend money on it (via your iPhone) if it doesn't change your experience as a user. I'd expect you to at least see some change, hopefully in the form of funds in your own paycheck.
Is there something special about users that buy ads that means Apple can't get a cut of their purchases, or that we don't consider them Facebook "users"?
I think the above comment was more about Facebook being somewhat hypocritical in complaining recently about the one time they do have to pay, despite the fact that in most of their business they don't.
