Absolutely right. The only difference between alleged platforms is how the platform owners treat their devs. All platform companies face the same issues of balancing developer trust and the ensuing added value and their own strategic imperatives but not all platform companies are alike. Companies can have very different cultures and very different attitudes to third parties with whom they have business relations. The fact that they CAN turn on their own on a whim doesn't mean that they have to or WILL. So stories about the documented behavior of any such companies are very valuable to devs.
