Ah, now I see. It makes perfect sense. Think of it this way.
1. People who pioneer the use of alternative browsers always have high intelligence.
2. However, some browsers lack the ability to appeal to anyone beyond that initial market.
So know the graph is just saying things we already knew. Opera has a tiny fanclub, but the browser doesn't appeal to many people, or Opera fans are just bad at evangelizing to their friends. Meanwhile Chrome and Firefox have a much greater mainstream presence, and hence an attenuated average IQ.
So Opera's concentration among intelligent users isn't an indication of quality, but rather, some problem in their marketing approach.
