Personally I don’t want to support Microsoft bing either. This website you shared doesn’t lump together all the bing using search engines (DuckDuckGo and yahoo). How is supporting Microsoft a wayyy better choice. This isn’t some pump and dump scheme. Your criticism should be of the company (they added referall links to their browser and the owner has some nasty political takes on top of running another privacy invasive company).
I know the search is not but I thought the browser was on GitHub
