Yes, it seems to be the case. Yes, it alarms me too. The question is what can be done about it? There are supposed to be good alternatives to Google, but for whatever reason search engines keep disappearing. Here is an article that I read about that: https://archive.org/details/search-timeline

I think that before progress can be made, someone has to figure out if it really is just super hard to make a search engine (and if that’s the case maybe solutions can be found depending on what the specific problems are) or if there is something else going on. I think the only way to do that might be to try making a search engine and see what happens.
