I am not saying that many people use Bing. I am saying that this kind of intervention would be a big story either way, because there would be people rightfully complaining that the government actions supports monopolists position.

I use Bing myself. Most of my searches are just hard urls or reddit+topic and Bing doesn't poison my results with amp links that don't retain my setting to use the browser and not the app. If you hate amp links like me then Bing is great.
