My point wasn't so much about maximizing profits; it was more that these free-service companies might not even be tenable (at least at their current scales, or anything like them) with the drastically lower profit-margins of traditional ad impressions.

And my thought is, a zero-or-negative profit margin might very well be. It costs a lot to run Google/Facebook/etc. — probably a lot more than it costs to run the types of services they compete with. For the companies to not go bankrupt, their ad clicks/impressions need to be of at least as much value as their CapEx+OpEx. With adtech type ads, they certainly are at least that valuable. With only traditional type ads, would they still be?

I'm not arguing that these companies should be allowed to do this because they have some fundamental right to exist, mind you. Just pointing out that taking adtech out of the equation could "pop the bubble" drive margins negative, and just erase the whole free-ad-supported-services market entirely.

(Consider: why don't traditional-ads companies offer free web services supported by said traditional ads? Is it only because nobody cares about buying placement with them when targeted placements are available from Google/Facebook/etc.? Or is it because, even with full dealflow, it's still negative-margin?)

Tracking doesn’t actually add that much to how much they can sell advertising for. As to traditional advertising companies it’s simply a question of competence, you may as well ask why they don’t sell vacuum cleaners.
