I’m puzzled. Do pedants not accept that language evolves?
I agree that decimate does not mean annihilate or exterminate, even in the Oxford Dictionary of English, but if as pedants we only ever use the original meaning of any word -usually listed as ‘historical meaning’ in a dictionary, there would some very stilted conversations going on.
Never mind. Merriam-Webster put this very simply.

Well, Mollygo...

We have to accept it. That doesn't mean we have to like it.

As you just managed to use two words that accurately describe the situation that people wrongly use 'decimate' to describe I can't see how it would 'stilt' a conversation to use them.
I'd always understood that one of the glories of the English language is that it has, because of its historical origins, a wide choice of words with which to precisely and unambiguously convey ideas. Language is about communication, after all. Using words correctly means that the person you are communicating with doesn't have to perform mental gymnastics to work out what you mean.
Saying 'it doesn't matter' if words are used wrongly turns the language into an amorphous mess, IMO. I just prefer not to have to perform mental gymnastics...
Dictionary compilers are always at pains to point out that they follow usage, not proscribe it. But if people used words correctly their meanings wouldn't change... It always seems like a bit of a chicken and egg situation to me.
