OpenAIs response: https://openai.com/index/apple-is-getting-this-wrong/ Personally, this reads a bit ridiculous in the face of what Apple is claiming but time will tell.
IP disputes between some of the richest corporations on the planet don't get a lot of sympathy in the court of public opinion anyway. Even if they did, what difference does it make? There isn't a sheriff or DA with a public face that has to make a decision here.
