Surely it's not actually possible for apps to listen in on audio 24/7? At least on iOS, you would be notified that this is happening? Or am I being naive?
I have the same question. Both Android and iOS have privacy indicators [1]. I'm still unclear as to whether the claim being made here is
1. that CMG active listening can bypass these indicators (concerning), or
2. that Google Home/Siri/Alexa recording data can be sold to 3rd parties.
