This is not Chrome's purpose. Everything between the user and the monetization mechanism (advertisement) is strategic to Google. It just doesn't sound as warm and fuzzy when they say it like that.
The two statements are not necessarily in conflict. It helps Google's bottom line to move the web forward, and make more things possible through browser interfaces.
So close... add a couple more details:
- Google makes money from ads
- Promoting open web technologies reduces the stack they have to support
- Promoting open platforms removes roadblocks to reaching customers
- Supporting "competitors" that provide revenue generation channels ensures that even when the lose, they win.
Business is not warm and fuzzy. For that, you need to go non-profit. Look at these and you can see that Mozilla is really warm and fuzzy: http://www.mozilla.org/en-US/firefoxlive/
