Their business model is/was selling users' data. I met several sales teams at Opera back in the 2010s while I worked with one of the world biggest smartphone seller (i.e we chose which app to preinstall on zillions Android devices). They had no shame explaining in details how we and our partners data could use the data to profit against their very own users. How could one imagine using their product after such cynical presentation? I wish this was better known.
