I do not think so. A group of friends vs a group of people collaborating through internet is very different thing. I would be okay if rules simply say no discussion or talk outside of work we collaborate on.

But it is very likely same sensitive people will jump and say "how can one be quiet when XYZ minority group is getting harassed/attacked/bullied/doxxed ? Say something don't be quiet on grave injustice." By saying something most likely means always in favor of over sensitive folks. If one tries to bring in different POV which does not fit the offended person's worldview, the person who said something is now racist or some kinda anti-minority douchebag.

So to me COC have one main point that is to attack on people who you do not like.
