It looked surprisingly pretty weak to my non lawyer eyes. I mean I fully understand that apple business practices are building a moat through highly integrated software but its almost a feature for their system and you buy it knowing that. It feels like it goes back to Android vs Apple approach to their ecosystem.
It's not merely the integration which is a problem, it's how that + network effects gives apple undue market power to dictate terms to its users, devs, etc.
Being a middleman between users and devs, say, takes on a different character when you're a 2-3T biz at the heart of the economy.
