Weatherman introduces fruit-based authentication system to combat deep fakes

It's probably not hard to deepfake him eating a fruit.

The win of what he's doing is probably a lot more social than technical. It's funny and calls attention to the problem, which brings a lot more people to report the fraudulent channels.

It likely gives him some virality (I for example would not have seen the video if it wasn't for this)

And also, it gives his loyal followers more reason to check his website directly.
