A different matter without distinction. Apple is equally as unaccountable as OpenAI and Microsoft, their only difference is their usual marketing strategy that the industry never took seriously in the first place. If it came out that they were sending the NSA all of your "private" LLM requests (like what happened with push notifications[0]), Apple would just sheepishly admit it and continue advertising their same security-oriented shtick. They're shameless.
