Yes, there is Apple Search Ads thing which allows to advertise an app on App Store. The thing is they are transparent on how it works and explicitly say that they don't sell any data. See here: https://searchads.apple.com/privacy/

Thanks for your post but your Apple section is questionable. Could you please provide sources for your claim that Apple sells data they collect? Also, after that Qualcomm f*ckup, using T1/T2 vulnerability as a reason not to buy Apple device is weird. The only valid arguments are all outlined in the Gist and they are surely concerning. But that’s not nearly enough to say that Apple devices should be avoided.
