This WSJ story has details about the FTC recommendation to sue Google (overruled by the commissioners at the time). They accidentally sent the WSJ every other page in a botched FOIA request.

Starting with the recent EU decisions is probably a good bet. There are three fines the EU imposed: https://en.m.wikipedia.org/wiki/European_Union_vs._Google#EU...

Just one point, but I know that we submitted a complaint to the DOJ about Google’s sudden maps and street view API pricing changes. Their “free until there’s no competition, then we take all of your money” business model fits in the antitrust regulations. We’re hoping they include that.

This is just speculation, but I read somewhere recently that alleged that Youtube wasn't the gift to the world it appears to be. While I love Youtube for the most part (Free, High Quality), it is strange that we haven't seen much competition. Maybe it's a loss leader for Google and nobody else can afford the expense, or maybe they're doing something shady to make sure nobody else can afford to compete.
