That does not make this thread's OP incorrect in using it. It does mean, though, that you've essentially dropped to character assassination, simply because you don't like him using it in the recently dictionary validated way.
Now that the usage is officially correct, after being added to many dictionaries over the last few years, people need to just get over it. That means, that when someone uses it, changing:
"I *hate* that, it is incorrect usage"
"I *hate* that, it *should* be incorrect usage, so I'll make up some arbitrary insult about that usage, due to my emotional dislike of it in that context."
Realistically, you (and others in this thread) that dislike this word, in this usage, are suffering from "old man" syndrome.
The world is changing! Everything has gone to weed! Bah!
Embrace change, in a dynamic language.
NOTE: I say this as someone that *hates* incorrect usage. Its versus it's is my big "bah". I keep posting crap like this:
"How to keep its and it's straight! It is the same as hers and his. Why?
Well, my premise is that it used to be "hes", but morphed to 'his' over the years. So:
he => hes => his
her => hers
it => its"
So.. I DO SYMPATHIZE. However, if its and it's were somehow merged in the dictionary, I think I'd have to give it up.
The war is over. The battle is lost. There is no going back, no reversion, for literally all eternity, literally has changed.
The best you can hope for at this point, is that in a few hundred years dictionaries change that second definition to 'archaic'.. like I've seen for some other words.
