It's great advertising.
I think Google is doing some of the most impactful security work as a company I have ever seen. Between GOOG and MICROSOFT (within past few years) they have been instrumental in moving the bar and the industry. They both catch flack for the privacy issues (which is a leg of the InfoSec triad) but I think most people should be grateful for the work they do.
Products like Coke are internationally recognized but recognition != likeability, which is why they continue to pour in big $$$ in advertising.
This is advertising BigQuery[0] which is a Google Product people may be less familiar with. This nicely shows off what can be done using a large dataset.
I'm grateful for the work they've done here, and I have no doubt individual employees donated either their free time or 20% time (or w/e it is now). But that doesn't negate the fact that this is an advert for BigQuery.
