Because it's true.

Scrum is like Spaghetti Carbonara in America. The ingredients are simple and there's a tiny bit of technique involved that anybody can figure out after a few tries. For some reason though almost everybody that makes it decides that they know better than the people that invented it and so adulterates it with peas and onions and garlic and cream and cream cheese and Italian seasoning and parsley and chives until it ends up being Olive Garden Alfredo. If they wanted Carbonara then they would have cooked the Carbonara, not the waterfall with a bunch of JIRA workflows and four-hour meetings layered on top. They just did what they would have done anyway while attempting to sound fancy via obfuscation.
