From a perspective of someone who might want to advertise I want to make sure actual potential customers view my stuff. The pitch for tracking is snake oil so Google et al can pretend they're delivering that without doing the actual work of properly generating leads. Or finding good ad venues
The person/company that's actually selling ad space is not the problem in this discussion. Google just makes selling ad space (much) easier than directly contacting brands would be.
