What I did was a "fake door" MVP, as the article states. It is not necessarily intended for directly measuring sales but whether its worth my time to build it in the first place. Having over a thousand sign-ups now, it validates that I should indeed spend my time on it.
Then, I would make a high fidelity one, a "one feature" MVP as the article calls it, which would cut the product down to its essence and see if it can still solve a specific problem, and whether people would still pay for only one feature. I am doing this now with a mobile app instead of web/desktop app as the reduced screen space forces me to think about the problem of time block productivity from its essence.
Perhaps your definitions of MVP are different than others, which is perfectly fine. There are others I've seen over the years like simple, lovable, complete (products), and so on (https://news.ycombinator.com/item?id=22955085).
That he's denying this proves your point.

> You're twisting the meaning of the words in the acronym. I really don't care, but it renders the words meaningless to use them that way.
Again, I'm not sure how to explain that MVP does not literally mean an actual product. It's a tool for hypothesis testing, you don't spend time and energy building out your entire product before you show something to customers, that would be a waste of time and energy. That's why I, and others, define MVP as anything that let's you understand something new about your market and eventually you use that knowledge to make a product.
