If you create tools that can be used maliciously against people without at least attempting to prevent misuse, you actually created a weapon.
Techbros try to sterilize the situation with their neutrality because that's what their FOSS ideology asks of them. Inaction is also political. FOSS is not a shield for you to protect yourself from social responsibility.
Platforming racists/facists by giving them access to your tools gives them space to hurt people with their ideas; making you complicit.
