Bing often removes websites from their index but this does seem very weird. I don't know why Bing would remove a privacy blog from their search results but this also shows how so many search engines are dependent on Bing or Google for results. The only search engine which isn't dependent on Bing or Google right now seems to be Mojeek and Metager (Searx is just a meta-search engine). Mojeek is probably the most promising but right now it's results aren't the best but the results have been getting better. But I do wish that DuckDuckGo indexed search results themselves so they don't have to deal with Microsoft's decisions (also being reliant on big tech to start with isn't a good thing for a independent privacy-focused search engine.
