Last I saw, the FreeBSD code of conduct is a list of things you can't do, so it's easy to interpret that as "anything that isn't explicitily denied is allowed", and it only disallows negative comments that"reinforce systemic oppression" against certain groups (ignoring that opressed groups can vary across the globe). I don't use FreeBSD, so their CoC has no impact on me, but it's far from neutral.
