By the way my suspicion is it's not Apple selling voice data to Google. My guess is the problem comes from apps accessing the microphone surreptitiously. I actually think Apple knows app vendors are doing this and they are planning to out them in the next operating system update that will add a little light showing whenever an app is accessing the microphone. Like they did with outing those cache exploiters.
I think they know tightening up privacy can be a big attack on their major competitors.

Android 10 shows an icon when an app I accessing the microphone (unless it's only oxygen os, but I doubt it).
But it's still scary to see stories like yours.
