More interesting to me is the fact that tech companies are finding it surprisingly difficult to control where their ad-spend goes. I suppose this is an inverse of the problems with supply chains, where Apple can take three years to get a connector vendor out of their supply chain even when they were using literal child/slave labor. It's a market for lemons; bad "money" (publishers, suppliers) drives out good. The question is: will questionable ad publishing actually harm corporate reputation to the point where big ad spenders go away, or will we just see periodic Adpocalpse-style waves of spending being decreased and then brought back?
