If Appledystopia is right in its 2020 article, Microsoft loses US$1·5 milliard per annum on Bing. So maybe that explains why it’s worsened so much. Microsoft might well be finding ways to cut its losses, and servers cost money. Pity that none of the Bing clones are saying anything, not even Duck Duck Go’s usually vocal CEO.
I’m glad I discovered Mojeek when I did. We lost some traffic with Duck Duck Go’s near-dead internal search on Lucire, and overall I suspect everyone has lost traffic with Bing dying. With Google now also faltering (they still make plenty from the human farms, but you have to wonder just why it has worsened, even for existing sites), then it’s important that alternative, growing search engines—that’s engines, not services (so you can discount Ecosia, Neeva, Qwant, Duck Duck Go, and many others)—get our support.
There’s really only Mojeek in the occident with a growing index, regularly requiring new servers. If you aren’t anti-Russian, there’s Yandex; and China of course has Baidu. Brave and Yep are making great efforts but their indices are still small, though Yep can do better than Bing on some sites.
