What kind of "free" apps are you talking about? I'm talking about a "free" app where I download it for free, then I click a link in my "free" app that takes me to Amazon's web store where I pay with my credit card to buy stuff.
Is that the kind of "free" app you're talking about? Or are you talking about something else? Because I don't think Apple is taking 30% of the other kind of free apps, the ones that don't involve me paying for things with my credit card.
I admit I was talking about the latter. I went with the tl;dr, didn't read your blog post, and made the assumption that you were talking about all free apps, not just the apps with paid subscription content being served through them.
That still leaves a lot of app developers who aren't Amazon or a large publishing house. Could be a pure SaaS company (whatever that means) that later came out with a native app. Or an app that falls in the gray area of charging a subscription for functionality but yet still handles "content," such as Readability or Instapaper.
Were all these developers expected to assume that they would become targets? I imagine this is where we still disagree. But do let me know if you were only talking about Amazon and other large content publishers.
