The interesting message is that you can recognize these sorts of behaviors and then shut them down. And when you see them persist in a person you can better manage that person's role to be non-destructive.
Par for the course these days. I feel like we are on the verge of an ad revenue bubble collapsing, there's not much more that can be done to make the ads more intrusive unless you get rid of the content altogether.
Incidentally, that's basically what the print version of Forbes has done...they now have sponsored content which are basically ads masquerading as articles written by Forbes.
