As an Opera user
I would find that sad news. I rarely use Opera turbo/mini these days, so the privacy issues aren't much of a worry for me although they would certainly exist. And for Opera, greater exposure would be nice, web developers might actually begin to acknowledge its existence.
I do worry that the browser would become a social Facebook interface covered in branding and unremovable methods of 'liking' things. While gradually losing anything that might, one day, possibly cause a typical Facebook user confusion. e.g. Dragonfly, mail, feeds, right click, windows, user scripts, ad blocking capabilities
