serious question: how does opera (the company) make money?

tbf it seems to be a common issue with search engines atm. brave also has the stupid ai response topmost, and startpage without adblock pushes in so many sponsored results that you need to scroll to get to anything else

i trust proton quite a lot, but the open source part seems to be only partially true. on their github, i can only find client side code (ie. browser extensions, mobile apps), not the server code, which bitwarden does publish
