I don't think the admins are against input. If they were I wouldn't even be allowed to say this.
What they do from time to time is act clumsy in laying down their boundaries. They're absolutely right to say it is totally unacceptable to make the far right argument of Israel controlling da wurld. Which is really all that they are saying with this post. The issue is that they get this across in a way that implies there is a problem in the wider userbase's nuanced takes, which there almost always is not, and when this is taken the wrong way people negatively react because they do not want a chilling effect on debate about the nuanced entanglements.
