This is just stupid. The link they are banning doesn’t even TRY to bypass the rules, but because it POTENTIALLY could, the apps are being banned.
Apple is going about this the wrong way. Now, to buy a Kindle book, I’m forced to use Safari, instead of the much better user experience of just doing it in App. What they should do, if they are so concerned about bypassing the In App Purchase system, is only allow paid apps to bypass the In App Purchase system. That way they make money and make the experience better, instead of the opposite now.
