The claim that an adware company can listen surreptitiously to users seems questionable to me. Every large consumer hardware maker I know is TERRIFIED of losing customers’ trust when it comes to voice/video recording. They go out of their way to prevent surreptitious recording by *anyone*, including themselves.
Is it possible that some unscrupulous maker allows surreptitious recording, intentionally or because of an unpatched bug, that this adware company is exploiting? Yes. Is it likely that a mainstream phone or smart speaker is allowing this to happen? No, at least not for long once they discover how their measures are being circumvented.
I take this company’s claim with a big grain of salt for now. Hardware companies know that allowing trust-busting behavior like this will tarnish their name. There’s not enough money to be made from this abuse to justify losing future hardware sales.
