Because it's much better for the consumer to search for a city, get an interactive map right there on the search results, but no link to jump to Google Maps so they can get an estimate on how long it takes to get there, because that'd be bundling.
I'm talking more about them posting new product launches, I/O livestream, gmail pinned to the top, etc. Embedded stuff in search results is fine for the most part, although their intent their is primarily to prevent click throughs to other sites and increase the chances of an ad click
