I am not against this suggestion if only for the reason that the bulk of iOS App Store revenue comes from freemium games. The money that Apple is making from non-gaming apps is likely less than 5% of overall revenue. The amount of money given up in exchange for avoiding all that bad PR would be a rounding error on Apple's balance sheet.
That said, why only games? The only reason I can think of is their business model - games, like most other software distributed over the internet, tend to entail high fixed costs and low / zero marginal costs. The very sort of business who can survive being taxed 30% by Apple. And if we use this line of reasoning, there really isn't any reason to carve out an exception for companies like Netflix who face a similar cost structure.
My understanding is that this is the result of a settlement with Japan's free trade commission. Apple did not create the reader app rule out of some sense of altruism.
Apple will let developers of “reader” apps around the world link to an external website to set up or manage an account beginning early next year.

So I am guessing that if Apple had their way, the reader rule wouldn't have existed either.
It's also what Apple, in all their self-righteousness, seems to genuinely believe (I assume you are referring to the press release below).
Today, the European Commission announced a decision about the App Store and competition in the digital music market.

I guess my response would be a somewhat sheepish "Well, Apple isn't entirely wrong, but they aren't entirely right either". Apple has done a tremendous amount of good for developers by them creating the iPhone in the first place, by popularising the concept of an App Store to the mass market, and by continuing to improve on it year after year. You just need to compare it with the Android play store to realise that while not perfect, the current success of the iOS App Store wasn't by chance or luck either. It happened because Apple really invested a lot in developing it, the same way you would tend to a garden.
If there was one criticism to be had of Apple's response, it would be their lack of acknowledgement that developers too have done a lot for Apple and the App Store. I mentioned how I use a number of iOS-only apps, and credit to the developers for pushing the limits of iOS and for not abandoning the platform even when Android came along (though the money on iOS is good too).
Would Spotify have seen the same amount of success today if we were all still using blackeberries and Nokia phones? Who can really say. The issue is that Spotify hasn't exactly been entirely honest or forthcoming with their claims against Apple either.
I dunno about this year's WWDC, but it seems like it might get a tad awkward.
