Maybe they have and Bing just prioritizes requests differently?
This is interesting though, when I saw the headline about Microsoft making so many takedown requests to Google I assumed the items to be taken down were found by the Bing team, but it seems that isn't the case.
Maybe it is and the Bing team only uses Google to find the links. (lol) Actually didn't Microsoft force their employees to use only Microsoft products? Sometimes it's not fun to eat your own dogfood.
As far as I remember, it was them asking not to buy iPhone. Nothing more. They can't force their employees to use only Microsoft products. They'd be down in a day!
