Their whole argument is based on this sentence. So I'd expect some rationale. Instead, they provide as "example" links to Google, Microsoft and Apple. The funny thing is that the one by MS is probably the most criticized one, with the company partly backpedaling on it. And Apple is often criticized by LLM aficionados for being quite conservative. Google is the one proposing it.

So my question is: are browsers and operating systems really expected to gain access to language models? If so - by whom: the users or LLM vendors like Google?
