David Walsh, Armstrong’s journalist nemesis, has made an entire career out of exposing Armstrong. Yes, there was an ethical motive there to keep the yellow jersey to those who deserve it, etc but I doubt we’d have heard of the Tour de france doping scandal if journalists had to do it all for free.
The same goes for the Boston Globe when it came to exposing widespread paedophelia in the Catholic Church, or Lawyer Rob Bilott when it came to suing the DuPont company for poisoning thousands. Clearly an ethical motive in there, but the financial motive plays an important part. I don’t think there’s anything wrong with that, if you work hard enough to expose wrongdoing on these kind of scales you deserve a payday in my view.
