Urgh, I know that it's a solid explanation but I hate the "it may not be true but it captures a truth that people feel" argument so much!

See also "instagram is spying on you through your microphone". It's not, but I've seen people argue that it's OK for people to believe that because it supports their general (accurate) sentiment that targeted ads are creepy.

I used to be sceptical of this claim but I have found it increasingly difficult to be sceptical after we found out last year that Facebook was exploiting flaws in Android in order to track your browsing history (bypassing the permissions and privilege separation model of Android)[1].

Given they have shown a proclivity to use device exploits to improve their tracking of users, is it really that unbelievable that they would try to figure out a way to use audio data? Does stock Android even show you when an app is using its microphone permission? (GrapheneOS does.) Is it really that unbelievable that they would try to do this if they could?

If they are using the microphone to target ads, show me the sales pitch that their ad sales people use to get customers to pay more for the benefits of that targeting.

(I have a ton more arguments if that's not convinced enough for you, I collect them here: https://simonwillison.net/tags/microphone-ads-conspiracy/ )

I get your point, but can you point to a sales pitch which included "exploit security flaws in Android to improve tracking"? Probably not, but we know for a fact they did that.

Also, your own blog lists an leak from 2024 about a Facebook partner bragging about this ability[1]. You don't find the claim credible (and you might be right about that, I haven't looked into it), but I find it strange that you are asking for an example that your own website provides?

That claim is SO not credible that I think serious outlets that report on it non-critically lose credibility by doing so.

Seriously: the entire idea there is that there was a vast global conspiracy to secretly spy on people to target ads which was blown wide open by THIS deck: https://www.documentcloud.org/documents/25051283-cmg-pitch-d...

I have already experienced the benefits of sending this to several family members, and I'm thankful for the hard work you put into laying everything out so clearly
