Even worse? Someone (who didn't coin the term) is trying to trademark it.

You know, to "protect" it from dangerous people. Scary stuff. That's one of the reasons I'm clinging to it - so Aleron Kong doesn't end up with final say on what is and isn't LitRPG. You wanna talk about cynical. ;)
Anyone that wants to do that deserves everything they get when they get exactly what they want. Which will ultimately be responsibility for maintaining and keeping up discussion around the term – which won't happen, because the be forced to defend the trademark lest it fall into legal limbo.
The worst thing that can happen is his own success.
