What they need to do is to find a way to pay their bills. If ads allow them to do that then it's great (maybe non-personalized work well enough? Or contextual targeting, as others have suggested in this thread). If users cannot stand the increasing amount of ads then they will stop using their service. Or maybe these companies can adopt a mixed model where people can pay to not see the super intrusive ads, and everyone else gets the ads?
I am not sure what your point is.
