Ok? It's an incorrect usage. As somebody who was in on "Agile" since before it was "Agile", I'd say much of what happens in the "Agile" world is an incorrect usage. So it's no surprise to me that another term has been misappropriated.
The key concept has been widely adopted by the agile community. I have encountered the problem where project managers have mixed the startup MVP concept and the agile MVP concept up though. So, I guess you have a fair point.
Again, so? The "agile community" has adopted the notion of a "daily standup" where nobody actually stands up anymore. The "agile community" doing something a particular way isn't proof that they're doing it right. Indeed, given that the "agile community" these days seems to mostly consist of non-agile companies agile terms for non-agile activity, I'd argue it's evidence the other way.
