I think the article basically reiterates the old canard that an artist must suffer for his/her art. That may be the case for a good number of the geniuses who have contributed to the collective art of our world, but I don't think it is a necessary attribute. I do believe photographers (and artists) see things differently from most people, and as such, they react to the world (reality) from a different perspective. Because of this, they are often misunderstood, but that doesn't make them troublemakers. It does make them nonconformist as a previous poster has suggested. On the other hand, photographers such as paparrazi (perhaps mere picture-takers) seem to often be troublemakers, but that has little to do with their creative, artistic abilities and more a function of their lens size and stamina.
