That would make sense if Microsoft didn't own Bing. But they do, so that makes no sense at all.
Why, it does. When you don't have a working product for a market, you don't pretend you do.
Are you also against Microsoft's usage of Github and Linux since the own competitors to those? Should they stop making Office for iOS and android?
I use Bing to search technical and English contents. I think Bing is better than Baidu on this point. I think google is better than Bing, but I cannot use google naturally in China.
