It’s an interesting framing because there’s a debate about how open the Meta model actually is. It’s not a truly open platform like Linux, the example Professor Cusumano mentioned (perhaps why he chose the word “model” instead of “platform”). Meta doesn’t want you to run different operating systems on their headsets, for example. But overall, Meta likely puts fewer guardrails around what developers can access and has less stringent requirements for publishing on their platform compared to Apple.
