Go to google. Enter search for something very specific like "red baby buggy bumpers." Google decides for some reason that I didn't really mean "red" so it excludes it from the search. Now all my results are randomly relevant. I have to find the little link that says "Include Results with 'red'."
Which.. to the google engineers, why do you think I typed that in the first place? Just to waste my own time? Who are you to drop words from my query? I'm not interested in a page of results, I'm interested in ONE RELEVANT thing.
They've intentionally made choices that make the product worse. This is just one, I could type up a whole chapter on this anti-pattern nonsense. All they care about is worthless KPIs that don't correctly measure "quality."
