"Worked." How are they doing now? It's a cats-outta-the-bag situation. What DOES makes invasive tracking a necessity is it works so much better than the free models that came before it. If you're not doing it, your competition is, and they're getting one up on you. I don't think we have a free model that monetizes more efficiently than invasive tracking, so the only option you're left with is a not-free model. And for consumer-social, "not free" is a small niche (eharmony comes to mind as making it work, but even they bought all the free dating companies because the free ones were eating the market...)
