I've seen more 'moral courage' from cartoons on the internet than doxxed people like Sam Bankman-Fried, Su Zhu, Do Kwon, the people who ran Celsius, Jordan Peterson, etc.
If the students added their names, it would do nothing to enhance their story, and everything to put a target on their backs. Especially when they are undergrads, and have zero power. This is how they speak truth to power.
But if you still disagree, prove me wrong by enrolling in a college and seeing how far your idea of speaking truth to power gets you.
