But the fact that you can have at least one alias for your account (doesn't have to be from any other service), invalidates the issue. It's a social network (according to their definition) AND you can have different "identities" linked to the same account. Anyway, this kind of disputes won't be solved in an online forum. Besides, I don't think that MSFT and Google are willing to battle for this kind of issues right now. It could trigger a HUGE battle regarding all kind of assets (OS's, office suits, search engines, etc). Most probably, they would simply make a some kind of cross-licencing and forget the whole thing.
