It’s so incredibly unlikely that any company would make that investment just to spy on the conversations of ordinary citizens when there are far cheaper and easier ways for them to build and sell advertising profiles.
Ultrasound is used by Microsoft teams, some apps use it to transmit data between phones. Back in the day there was a chrome app to transfer links.
Amazon sidewalk already connects devices together. Samsung Smart things already bridges Samsung devices. Apple Air tags already use “primary” Internet connected devices to transmit data about “secondary” devices.

None of this is new tech, it’s all feasible.
its not unlikely, devices were already shown doing shit like this
