Correct me if I'm wrong, but my understanding is this lawsuit was limited to OpenAI and Apple conspiring to bury xAI in the App Store (like you know, 99.999% of all apps are by default), not that you are forced to be using a particular LLM built into the OS. Which on face value, is a really stupid arguement. OpenAI was out first and had millions of users before Musk even formed xAI. So of course it would get promoted for its userbase and popularity.
