I think it's because Apple would have to provide every competitor (including ones running off-device with no confidential compute) with the same level of access Siri AI would get, which poses a lot of security and privacy concerns Apple would never allow third-party developers to get access to even with a TCC consent prompt (like reading and sending iMessages).

Which means Apple would have to give OAI and Anthropic access to Gemini, I mean Siri AI.

No, it's more that those apps needs to be able to make all of the tool calls Siri AI can make, which would allow third-party developers to collect data they shouldn't have access to.

App developers can already access the on-device foundational models through an API, but I don't think many developers want to do that because there are better models.

		Apple don’t want you to be able to say “Hi Alexa” or “Ok Google” to your iPhone, and wake it up. We have all kinds of data access controls, these could probably also be built around Siri and competitors.
