this has been going on for years. Google makes money with ads. the quality of search results is almost irrelevant to its business model
I’m willing to bet that >90% of Google Search users aren’t even aware that alternatives exist.
They are not suddenly going to stop using Google Search. There might even be a significant short-term increase in usage, for example, if they really need to go to page 5 to find the first relevant result.
They will use it less if it becomes a waste of time to try.
Over two years now I see specifically two people deterministically failing to find stuff through G search, and yet they still start with it in an almost Pavlovian ritual. Sometimes they will desperately scroll down, click on a blatantly irrelevant result and switch to facebook or some other bookmark aggregator of theirs to continue their brutally inefficient search process, thumb flick after thumb flick after thumb flick.
