SpaceX reportedly does not take kindly to criticizing the man at the top, Elon Musk. The space exploration company reportedly fired several of its employees who "helped write and distribute an open letter criticizing the behavior of CEO Elon Musk," according to Bloomberg. 

The letter was circulated with the point of calling on executives to make the company's work culture "more inclusive". "At least five employees" were fired, Reuters added, with the news being confirmed by SpaceX President Gwynne Shotwell.

Shotwell said in an email this week that the company had investigated and "terminated a number of employees involved" in writing and circulating the critical letter.
