Unless you use Siri, in which case random contractors might listen to anything you intentionally or unintentionally say to Siri.
You couldn’t pay me to use a voice assistant, much less would I ever have a voice assistant in my home (Dear God, it scares me that people do this) - but AFAIK Siri doesn’t do this like Google does.
The end result of this was, Apple brought the operation in-house and it's also now opt-in.
So Apple’s ‘focus on privacy’ is pretty much just PR bullshit, then. That sucks. Was hoping for at least one last bastion of privacy.
I believe this is the improvement you are looking for.
