Did you read the article? It's just one quote that shows the scale of his "art" production. It also shows he cared more about the output and money flow than what is actually printed and distributed under his name and signature. If it's not enough here is more:
> “(Dalí) was completely money obsessed, to the point of a mania,”
> The artist’s appetite for money ... made him a black sheep to many colleagues.
His greediness is the main reason the market of the fake lithographs exists in the first place.
