“It is well known among cryptography and computer security experts that closed-source software and algorithms are less secure than their Free and Open Source counterpart…. The very existence of non-free software and hardware puts humanity at a greater risk, it can foster or accelerate the process of the creation of an artificial entity that can outcompete or control humans in any domain, making humankind unnecessary, controllable, or even subject to extinction, and should therefore be considered unethical.”
