It might be different if anybody believed these celebrities were actively trying to defraud and harm people.
The reality is more likely that these people are effectively human billboards. People pay them to read a script, and they read it. Each week a different product, different script, same deal.
So they got suckered into reading an illegal script. They get penalized (rightly) but it doesn’t necessarily need to be extreme.
And now the SEC gets to show off their win using the same billboards.
