Re: Well he would say that wouldn't he?
Remember that MS is just Slurp Three, after Slurp One (Google) and Slurp Two (Facebook), so they are still playing catch-up - so while Google can see the ban as a way to hinder its competitors, MS see it as a stop to its attempts to catch up.
Hope you don't use any Google or Facebook service too... I think both have an enormous trove of images on their server they can still use to train their AIs... MS will need to buy some photo site to catch up.
