As for the second paragraph, Opera was actually strict pro-standard.. sometimes for their own bad.
Third paragraph is total bullshit. If anything, Chrome is the one copying from Opera. Webkit isn't "Chrome in a box" either. And pull of what this time?
As mentioned in my first paragraph, Opera has and had users, just not in your market probably. I written several times why Opera has users in certain markets, so just tl;dr: Opera was the best browser but was paid. Anything East from Germany didn't really care for paying for software (since it was insanely expensive), so they used the best browser out there. When FF was born, west switched to it (since it was better than IE). Opera went free too late, but managed to hold quite a big user-base in certain areas despite Google pouring billions into advertisement and producing chrome-only features. (another big contributor is Turbo and slow internet speeds, but I think it was a secondary factor).
ad EDIT: cry me a river. While I don't feel the need to downvote you, your comment did sound pricky enough to convince someone to do so.
