A sort of booking widget appears, taking up the space of the first 4 results. Instead of web pages we are presented with google place entries (another google project), and a dates widget at top, which when you fill it in leads to a nice list of google place results, so they are channelling users through other web properties they control.
This might seem superficially appealing to customers (personally I think it is great design, but used for evil ends), but it means that google controls that entire space, because people generally click on the first few results, and clicks after that diminish very very rapidly. So at some point when they start charging for google place entries or booking via google wallet or whatever, they can mint a huge amount of money purely because of the dominant search position they enjoy. They can also drive out of business anyone who wants to compete in that space, or force them to pay a toll to google - in fact I see they're already doing this as adverts for booking.com appear on google place bookings. Once we are used to them inserting non-organic results at the top of every search, they can start to charge for those results, and for everything associated with them. They will then have completed their transformation from a company organising the world's information to a company controlling and charging for the world's information.
As to maps, I think we need to clearly delineate between search results and mapping results. People would be fine I think if google offered a small option to go to google maps when you do an address search, but if they take over half the page with a google map on these results, it is legitimate to ask whether they are leveraging their dominant position in one domain to enforce dominance in another (classic monopolist behaviour).
This wouldn't be a problem if Google did not have 70-90% of the market share for search (depending on your country) - that is a near monopoly position. So Google are abusing their dominant position in search to promote their other properties, and to control which websites appear first in many domains (shopping, images, hotels, shops etc), and they are also in de facto control of the web due to their position in search, which is not good for anyone, least of all google.
