Yep. But for people like my grandma and parents it was absolutely true. My apologies that I have nothing to cite but my own experience and analysis, but closed ecosystems are a temporary solution, at best, for building trust in a new market paradigm. Any attempt to justify extending the life of a closed ecosystem once the market has matured enough to adapt to it will have a tragically shrinking effect on that company's market allowing other competitors to wedge themselves in by differentiating on greater flexibility and convenience.
