We have hundreds of thousands of people, including many dead people (or their supposed teams) suddenly deciding, within hours of each other, to sign up. We have had enough people explicitly say they'll never sign up ahead of time, and after their check showed up, they said they didn't sign up. And we had Elon Musk himself admit he's "subscribing" people objecting to the program.
I mean... how much more evidence do you want?
It's mass, MASS false endorsement. And that's highly ILLEGAL.
