Fellow comedians David Cross, Marc Maron, and Shane Gillis have condemned their peers for participating, citing Saudi Arabia's human rights record.
Their criticisms include the death of journalist Turki al-Jasser, a rise in executions, and lengthy prison sentences for social media posts.
Comedians are reportedly receiving significant payments for their appearances, but some, like Gillis, have turned down offers due to ethical concerns.
Human rights groups view the festival as part of Saudi Arabia's 'Vision 2030' initiative to improve its global image, while deflecting from ongoing human rights abuses.
