That deserves a source. Especially for "all cases"; I don't think anyone who understands machine learning could read some of his earlier papers and still think Ian Goodfellow invented GANs.
ex. in the article: "Goodfellow eventually admitted that my PM is adversarial...but emphasized that it's not generative. However, [it] is both adversarial and generative (its generator contains probabilistic units)...It is actually a generalized version of GANs."
When you're at "actually, probabilities means generative, and actually you know what, even my initial claim was too specific: turns out its a generalized version of GANs", all in service of arguing a paper should have been cited in another paper, years after the other paper has been published, there's not much room for sympathy.
