Google pretty well serves the wishes of their users, maybe not so well the wishes of a subset of site operators.
I put my my first site up in 1998 so I've seen quite a few come and go <G>
Google was like a breath of fresh air. It had a clean interface, uncluttered SERPs and it was way ahead of the rest in quality.
That was then and this is now.
The new Google interface is horrible with masses of googlespam, annoying videos and search results that move when you hover your mouse over what you want to click on thanks to popups; an invention of the devil. Try to search for what you want and they thwart you at every turn, showing you results based on 'authority' or a stack of obviously bought links rather than relevancy, whilst leading you into areas you never intended to go into.
Google are marketing geniuses. They gave away a first class browser, Chrome for free; it just happens to have their 'search' engine' as default, as well as advanced tracking systems. They nearly missed out on mobile but brought out a great OS and gave it away to all comers - subject to them being default search engine of course, which they now are on just about every browser and OS on the Internet after they cut deals with the owners (apart from MS of course, which has the dire Bing - hardly competition).
In the meanwhile G has become the bloated advertising agency it now is whilst other engines have quietly improved their offerings steadily. Sadly their marketing didn't keep pace. How do you spell Coil? Couil? couill Cewl? And who wants to type in 'duckduckgo.com' when they own the much easier duck.com? And did you see the laughable Bing 'howling' TV ads a few years ago? What were they all about?
Most people haven't a clue how to change from Google to a proper search engine. Even more don't know there are better options than G. However, like we now hoover our carpets with a Dyson or stick a Chinese bandaid on our cut finger we will eventually google something on Duck, Ecosia, or any other new entrant that comes along. Possibly one created by Apple to replace the billions they currently get from Google?
