I am not a lawyer. But you wouldn't be surprised to hear that

1. I don't have inside story of Bing in Germany. It could be that Microsoft either doesn't want to do it well, or hasn't yet done it well enough. I'm not promising either in particular, but it can be done.
2. Generally as an engineer you have a pile of options with trade offs. You absolutely can build nuanced solutions, as often the law and the lawyers live in nuanced realities. That is the reality of even the best sorts of tech companies who are trying.

My commitment is that maximalism or strict binary assumptions won't work on either end and don't satisfy what anyone truly wants or needs. If we're not careful about what it takes to move the needle, we agree with them by saying 'it can't be done, so it wont be done.'
