I was just trying to arrive at the conclusion of the article. I think it starts out listing reasons why developers choose to work on their own startups rather than join other startups. Then it says that the listed reasons are not really good reasons (they don't tend to produce impressive entrepreneurs). The conclusion seems to be that the respective developers would be better off joining startups instead. Hence my question if that would be more impressive than working on one's own startup for the wrong reasons.
Another way to interpret it would of course be to still opt for the own startup, but for better reasons.
