Lots of things that don't make a great deal of business sense still nevertheless occur in large corporations. Frequently. I'm not sure that's a useful metric by which to judge a situation.

I personally didn't reply to that other poster, simply because their tone suggested (to me) that they were more looking for an argument than a civil debate. Yours is very different, and thank you for that. This is something I'd genuinely like to bottom out, because from my perspective there's been a noticeable, ongoing decline in the quality of search results from Google.

So, challenge accepted. Here's an example for you, and it's not even that subjective: Run a Google search that includes a minus term and tell me how effective the search results are in regards to obeying that instruction. That was a feature I used on a daily basis until Google made it completely non-functional.

If you want an example that doesn't rely on specific features, trying searching for "<thing you might want to buy> review". Enjoy the avalanche of low-quality SEO and link spam you're about to receive.

Also consider the fact that many searches you perform on Google are already offered with a "reddit" suffix, because so many people can only find the information they're looking for by appending that term to their search. Google by itself just cannot find what you want any more.

If that's not enough for you and you want specific examples, that's certainly possible. I was searching for a solution to a programming related problem on Google just a few days ago, and came up empty-handed after 20+ frustrating minutes of it including "related" search terms that weren't relevant. Reconstructing that search wouldn't be terribly difficult, if there were an indication the effort was worthwhile. In the end I went to ChatGPT and got my answer, including a fully-functional example, in less than 30 seconds. An experience that is becoming more and more the norm as time goes on.
