>Better faith CoC people talk about freedom of association vs freedom of speech - if a platform doesn't like their oppponents, isn't it fine to ban them?

Sure, but the problem here is far more insidious. By latching into delicate and, at times, controversial issues, CoC may hold a project hostage and threaten character assassination.

Imagine that for some bizarre reason, CoC establishes that issues are only to be talked about on Mondays. People can comply, or they can leave, no biggie. Strange but clear cut.

Now, say it instead establishes whatever politically motivated consideration. The choice now becomes one of positioning oneself into the current political climate. This makes sense at times, but also leaves a door open for abuse akin to rules lawyering, gotchas and crybullying. Sometimes creates a phantom HR that has no interest beyond exerting its power and which does d with no accountability.

Problem is anyone raising this as an issue or rejecting such proposal is going to look bad while doing so. It's easier to keep your head low.
