alt Hacker NewsThe smell is that Apple doesn't want to give the same level of access to third-party AI assistants that Siri will get.
For what it's worth, Apple claimed they proposed an "equivalent access" framework with some kind of "trusted agent framework" approach, but that it was shot down by the EU. I suspect it was way more inconvenient for third-party developers than Apple lets on.
This has been the case for quite a while. Like Reminders - You can't replace the phrase "Siri, remind me to ___" with a third party app. I'm surprised the EU lets them ship Reminders there.
