I agree that the original meaning is more specific and it's a very useful one. But the role of this dictionary is to describe usage, and as you noted, usage on this one has definitely shifted over the last few years.
I doubt most native speakers who recognize and use this word are aware of the first, original meaning. So they're right to record it this way regardless of how we feel about losing that original sense of it.

You can disagree with this approach philosophically (but good luck lol), but it's the one this organization has chosen.
