I'm not looking to defend Gawker, but I believe that comparing it and its impact versus competitors/substitutes is absolutely relevant.
You see it all the time in politics where people are outraged at X when the other party does it, but can't be assed to care when X is done by their own party. They're lying that they care about X. The truth is they're using it as a lie for political power.
- "I think that this other person did a bad thing X."
- "You're lying, your other actions show that you don't really think X is a bad thing."
How is that an argument? The issue was originally that some other person did a bad thing X, but the second person above changed it to attack the first person making the argument, and accused the first person about lying about what they really think. Is this not an ad-hominem?
