You're completely correct, but that's not what I said...
Opera 15 is [just a] repackaged and rebranded chromium. It's not Opera or the presto engine, it's just chromium with Opera's branding and some other bells and whistles.
Opera went from being a distinct and relevant browser with a loyal following, to an irrelevant one.
I do not understand what you are trying to say. Could you elaborate?
