The blocking of competition was mentioned several times in the links I posted. Here's a couple of quotes:

> Google required direct partners to exclusively use Google's AdSense and could not engage with Google's competitors

> Google required that partners take a minimum number of Google ads and predominately place them above any other advertising, nor could place ads from other services above or alongside Google's ads;

> preventing manufacturers from selling smart mobile devices running on competing operating systems

> Google entered into anticompetitive exclusive agreements for the distribution of Google Search on both desktop and in the mobile arena

> The Commission’s complaint alleges that Google reneged on its FRAND commitments and pursued – or threatened to pursue – injunctions against companies that need to use MMI’s standard-essential patents in their devices and were willing to license them on FRAND terms.

Huh, I did not know about the Adsense one, that's news to me. Interesting to see if it's relevant in the U.S. because it was only with large partner contracts and Google stopped it before the E.U. investigation even began.

Again, the EU anti-trust law is different from the U.S. I already mentioned the Android Play services case already.

Anecdotal evidence, but if you don't offer GoogleADX inventory, your site gets de-ranked in searches. I am very interested in the anti-trust probe for that reason.
