I see hardly anything even about advertising in there? Let alone anything about ad blockers. It's just generic statements/quotes about monopoly, privacy, browser wars, etc... and a few notes about how promoting the web helps promote Google's products/services indirectly too, which helps their bottom line... which Google itself has been saying openly since forever. There's nothing there particularly predictive of this particular chain of events.
Would you happen to have any links to previous discussions anticipating this exact endgame?
