Yes, it's copied, and it doesn't acknowledge that the ideas came from your article (even though it attributes the drawings to you with a "Source" link).

I always thought that MVP by definition must be a complete product, but existence of articles like yours and Intercom’s Cupcake approach[0] makes me wonder what exactly do some companies out there consider as MVP. Some sort of incomplete prototype?
I noted below, that product people like Marty Kagan, consider a MVP to be a prototype where you test hypotheses. Worst case it can be discarded and a "real" product will be built after testing. It is a bit unfortunate in this that the "P" in MVP stands for Product.
Seems common nowadays. I saw a thread a few days ago where Nbdev did the same with terms they claimed to coin.
It doesn’t look like this article has outright copied yours though... the nice thing to do would be to ask permission to use your figures and link back
