Return of value is with respect to the costs of it. A lawsuit/brand value loss from illegally recording every communication you make (which we would have definite proof if it were happening, given that there our more phones than people on Earth) would far outweigh the tiny benefit (if any? I'm not convinced you would get any extra information in the general case compared to the tracking of the regular usage of your phone)

Also, I don't see the relevance of your second paragraph. The baseline is not "no ads", the baseline is "ads supported by all the tracking that Meta/Google currently does".
