This seems more like an Apple move than a Microsoft move. It's a pretty common opinion nowadays that Apple is the worst in the bunch; beating the pants off any unethical stuff Microsoft might be up to -- or was up to even back in the day. I'd imagine Microsoft just needed to be on board so that they didn't get left out and screwed over by this down the line.
I am completely mystified by how these companies get together and work with each other on things like this.
