Unfortunately MVP is one of those terms like "pivot" that got out of control. An MVP is "the minimum viable product is that version of a new product which allows a team to collect the maximum amount of validated learning about customers with the least effort."
This is a great example of a launch page, not an MVP. It's not 'a version of a new product', it's marketing information about a proposed product.
One reason it's a good example of a launch page is that it tells you before you enter your address that the product isn't available yet. Many launch pages these days talk about the non-existent product, ask for your address, and only then tell you the product isn't available. They try to start a business by lying to their prospective customers. I'm glad to see that this one shows integrity by telling the truth about availability.
This is not "a version of a new product," it is a screenshot of a version of a new product and a call to action. There is no product to evaluate minimally. Since you like definitions:
viable: Capable of working successfully; feasible: "the proposed investment was economically viable".
A minimum viable product is a product that's capable of working successfully; in this case it's one that potential customers can interact with successfully. This is not a product. This is a "coming soon" page.

This is a great example of an MVP. If nobody signs up, he knows there is no demand for this product.
