It’s scary how accurate they can predict you with what data they have; they don’t need to tap your microphone.
You’re on a OnePlus; there’s always a status bar icon if the microphone is active.
Think of what led to your conversation? Everything related to it you saw or searched online that could’ve later triggered you to talk about the subject, could also trigger them to serve you ads about it later. Perhaps your friend was the one, and the ad companies have linked you together, ie. by tracking your location and contacts.
And now you’ve noticed the adverts, you’ll notice them much more, where you’d normally ignore them completely. Furthermore, if you noticed these ads, you might’ve clicked them or stopped scrolling and stared at them too long in a wtf moment and now the ad companies know, so they’ll serve you a whole lot more of the same.
This is just terrible.
However, while it does add a layer of annoyance that’ll mess things up for most, like any DRM, it fundamentally is unsound and will get cracked. Us good people have a big incentive to do so here. Reading the spec, it still relies on a trusted party (expected to be the OS) and, unlike ie. games consoles, we already have admin access to that party from the get go.
Where it could be a problem is mobile phones. They could target browsers that support ad blocking and you’d probably need to root the phone to get past that.
Watch out I guess, because that opens the Emergency SOS page on my OnePlus phone and, if I have an additional setting toggled, automatically phones emergency services… the phone does not lock
