I always believed that it was kind of pathetic to profit off of others' stories and work... But that goes to show you that there is little to no altruistic intention. At the very least, with the secret writer type of deal, there is presumably permission to post after the individual is aware of the terms of posting. So in that aspect it isn't outright theiving.... Just a crappy deal.
A counterarguement may be that these individuals wouldn't make as much money because their accounts aren't as powerful.

Interested read, regardless of stance. Here's to hoping it stimulates intelligent discussion on both sides.
