Google has contributed many good things to the web, but they should always be scrutinized and challenged to prevent them taking over the platform to serve only their purposes. This is the same complaint leveled at Apple.
Google's involvement in the internet ecosystem exactly aligns with their profit motive: Putting relevant ads in front of individuals based upon data they've gleaned from relatively "un-sexy" sources like search, analytics, libraries, font hosting, email, chat, etc.
I'm not opposed to companies making a profit. I try, however, to keep in mind conflicts of interest when choosing my sources of information. Everything anyone at Google says about the web is suspect because that is a conflict of interest. Google, as an organization, exists to turn web traffic into profit and should always be considered accordingly.
