That's not the issue here. The issue is granting Sony access to the microphone. Sony, much like Microsoft and Nintendo, constantly monitor what players do on their consoles. There's enough of monitoring on their part while we're gaming for them to even listen to us without our permission, even when we're not gaming and the console is on "stand-by" mode.
Call me paranoid, but I already have a cover for the webcam in my laptop and tape in the microphones. I leave my cellphone in my room while I go dining with my family (and we all do that) so we don't risk family conversations being overheard by anyone.
You can put away your tinfoil hat, no human is actually LISTENING to your conversation unless it's exceptional and outside of what they've already heard in human speech patterns. These open mics are parsing key words, for all kinds of things, like selling you shit and human speech patterns to sell to AI companies and psychology marketing. 90% of the conversations are simply processed by programs, I highly doubt you're having a conversation that is that "special", they've been doing this for over a decade(or longer) now, they've heard it ALL already.
I do get that's it's a privacy concern, but it's a thing people will have to adapt to it's never going away, it's the "price" of technology with a microphone, I'm sure it's built into these companies business models that they're making X dollars off of selling all the metadata they're gleaming from all the open mics.
To think that your conversations are so exceptional that you don't have them around cellphones... that goes beyond paranoid, unless you're talking about matters of national security with your family.
