All in all yes. Sure they put Opera in there but those are actually very common and well known browsers. You know... IE, Firefox. (and Opera is still quite well known).

That being said it's their little war for total web control (again client+server+data) which is really bad, and what I meant to express in the comment.

They don't control IE, Firefox, or Opera. This seems really like they are fighting against Google's war for total web control. Which I'll reiterate, is a good thing.
