From what I've heard it is much harder at Apple to use your user data non-anonymized i.e they focus more on Privacy vs Google, Amazon etc where any team can use your data to do experiments and run A/B tests, ultimately what this means is that the quality of AI will be poorer. Developers of the $30 Google Home puck uses your data without thinking of the privacy consequences (internal bad actor), and hence is way better. This is what I've heard from developers/spokespeople of Apple. Has anyone else heard the same excuse ?
