Yeah people always say "They could sell data". I don't really see who would buy behavioral data on peoples browsing habits. That's fairly worthless unless you have a clear route to monetize it and connect back to those users. GMail has a clear route - they show advertising on gmail. All Opera could do is mess around with web pages, inserting their own advertising, or messing with content. Which would enrage users and website owners alike. As soon as they try to monetize, people will stop using it.
