> the definition of a platform being when revenue generated by software running on the device far outpaces revenue generated by sales of the device itself
They absolutely are. Apple makes money from the iOS ecosystem in two ways: through device sales, and through App Store purchases.
I'd agree that iOS is an example of a restrictive platform, in that ~30% of all revenue goes to a single gate-keeping party.
In any case, I messed up the quote a little, another commenter found the source and real comment: 'Gates said something along the lines of, “That’s a crock of shit. This isn’t a platform. A platform is when the economic value of everybody that uses it, exceeds the value of the company that creates it. Then it’s a platform.”' [1]
If that’s the litmus test - that the owner is a gatekeeper that keeps a share of the profit - you have to include all of the console makers and Kindle.
