"$100 million of competitive benefits to those accounts, harm to competitors, and harm to consumers."
At this point, there are "officials," with rubber stamps that are worth millions to a large number of businesses. Google, and facebook too. The difference between doing well or poorly on the ad marketplace, adwords, feeds, results, and such can be the difference between a business worth a fortune and one worth nothing.
It's similar in scale, incentive complexes and such to whatever public body approves real estate development plans. Friendly decision makers are worth a fortune. No details on who the culprits were, but it sounds like corruption near the ground level.... $100m. Different beast.
At this point, expect less criminally blatant forms of corruption to emerge. Hiring former facebook & adwords people as "consultants with contacts" is already a meaningful sized thing. Sound familiar?
