Ranting for the sake of readership, more likely. A journalist tends to write what sells after all, especially one who boasts about making money from your work :)

Yes, and they're doubly arrogant because they don't seem concerned with making money with it. The callus bastards. It's almost like they're just sitting there enjoying themselves...

callus vs. callous, related but not the same.

callus: A callus (or callosity) is an especially toughened area of skin which has become relatively thick and hard as a response to repeated contact

callous: emotionally hardened; "a callous indifference to suffering"; "cold-blooded and indurate to public opinion"
