fwiw Erik Kain is still employed at Forbes and appears to be basically taking the high road (not saying anything)....
I wouldn't call making some kind of joke or statement expressing his joy to be the low road. After all the shit Erik put up with because of Kuchera I'd say the guy deserves a victory lap here.
It definitely would be the low road and very unprofessional. I think he did the right thing by staying out of it. Heck he even went classier and wished Kuchera well
I don't blame the guy if he feels a bit vindicated by Kuchera losing his job, but he's smart not verbalize it if he does.
