But don't forget that they used their - for all intents and relevant purposes - unlimited budget to bundle it everywhere.
They were also advertising it on the front page of their search engine - a spot no one else has been able to reach AFAIK. I guess there's a lot more.
If this isn't monopoly abuse I have a hard time seing what is.
Or how when I signed into a Google account once for five minutes on my iPhone in a private Safari window and immediately got an email from Google inviting me to set up Chrome on my new iPhone...
