Think of it in a physical sense. OpenAI is a high walled castle surrounded by a physical moat. This protects them and their business model. Apple comes along and builds a super tall tower right next to the moat. They can now see into OpenAI’s castle, fire arrows, catapult in a giant wooden badger, etc. Even if Open AI copies the design of Apple’s really tall tower and built it behind the moat and castle walls, it wouldn’t do much because Apple still would be able to get stuff over the moat and walls. The moat doesn’t matter anymore for the most part. The castle (OpenAI) can be compromised and needs bigger walls, relocating to someplace with a bigger, or a way of attacking the tower (Apple). Copying doesn’t really accomplish any of those three.
