Words have multiple meanings. That can be annoying. It can be distracting. Sometimes (though not that often) it can be confusing. But even if we wish that only one of those meanings survive, that doesn’t make all the others “wrong” under any sensible definition of “wrong” that I can think of.
So if you want to say that you think “entitled” in this context comes across to you as unduly fancy, or as potentially distracting, or as just plain annoying, go right ahead (though you might be properly reluctant to condemn a fellow participant in a conversation on such grounds). But there’s no basis, it seems to me, for labeling it “incorrect,” unless you can explain who died and appointed you Usage King.
