Why would they replace Google with another bloated adware search engine then?
I used to be one of these people, not going to lie, but Bing is worse than Google when it comes to UX. The results are not as high quality, bloated and really messy UI.
I switched to DDG and then Brave Search later on and I can honestly say that Brave Search gets a lot of things right. Mainly the results quality and the clean UI and widgets.
