Google shifts their algorithm also in response to people gaming it. Affiliate websites (such as this one) have been gaming the SEO system with AI/India-written articles for a long time. It seems the dude is honest and writes the content himself, but it is obviously nearly impossible to tell them apart, so they all get the chop. Sucks for him, but perhaps we're all better off.

I'm saying both user preferences and search algorithms change. Even absent an algorithm change, it's not reasonable to expect search traffic to stay high over time. A drop in search traffic is always a potential, and one that exists regardless of any change in the search engine.

And it's also unclear whether algorithm changes - "Google's preference" as you put it - is a problem. Unchanging algorithms would likely trend towards a small set of incumbents collecting most search results. A shifting search algorithm landscape means users are more likely to see results that were previously buried. This story highlights one loser of this change, but not all the aspiring websites that would be eager to get even half of goodcheapandfast's traffic. These search results went somewhere. One site's lost traffic is another site's opportunity. Algorithm updates changing things up is not altogether an undesirable factor in a search engine.
