I think what makes it boring is that it's an informational piece, not a story, so I don't necessarily think it needs to be glamorous to get its point across. If I had one criticism to make, I suppose it would be possibly elaborating further on how they are treated by various Pirate factions. I can, of course, make my own conclusions, but a paragraph or so might be useful nevertheless.
As for the perceptions of capsuleers, I think the general theme common to any background could be described as out of place. Having extraordinary wealth to buy planets, political power to influence interstellar politics, combat prowess to dispatch thousands of people with relative ease... contributes to their inability to really blend with baseliners and be ordinary. That's not to say they can't mesh with them in other areas, but I think there's definitely an opportunity for character growth by exploring those differences and how these influences transform ordinary people. I think the article, specifically in discussing the jurisdiction of baselining in each empire, emphasizes that point.
Does that make every pilot a bloodthirsty, meglomaniacal killer?
I don't think so. Perhaps eccentric. We need only look at the 'capsuleers' of our own age, the wealthy elite, to see what kind of influence power and wealth has on people. From dictators, to media moguls, or even actors and other celebrities; once you're immersed in that kind of life there's a transformation that takes place that impacts us in a colorful way, and I personally find that very fascinating to explore.
