More like the advertisers who could cater to a person’s interest are not able to locate the individual.

Because the platform knows ads can be creepy, and will result in user disengagement.

Facebook often accurately targets people, and the result is terrified users.

So, the answer is other platforms have taken note, and are providing cover for users, to retain them.

This augments the return on ad spend, but only slightly, since ads actually aren’t very effective in practice. Ads are simply signage, nothing more. They don’t actually change behavior, but only reorganize behavior that usually would have happened anyway, so that the existing outcomes possibly land in the finite set of buckets differently.

Thus ad platforms only need to target so vigorously, and with that, it becomes obvious that targeting can be made less acurate, and buyers of ad space would never know.

So you can quickly see that Facebook’s game is absolute overkill, and other players likely underkill by a margin, with much improvement to their platform reputation.
