Yeah, that's a totally fair concern and is one of the points the episode addresses. Researchers acknowledged that the definition has broadened, but they also emphasized that it reflects a better understanding of autism as a spectrum. It does make the label less specific, but it's also helped a lot of people. Especially women and people of color. It helped them get more accurate diagnoses instead of being misdiagnosed or ignored.

Overall, it's a stat worth celebrating as it means more people are getting the support they needed all along.
