You're being disingenuous. It's a massive move that will dramatically lower the traffic to the subreddits, and was also done to the far-right supremacist and abuse subreddits before they were finally closed. It's the largest "anti-male-gaze" move possible without total sitewide banning.

But you set yourself a trap with the "well catered to by the administration" because you've defined this situation such that "catered to" is the equivalent of "done literally everything but gone nuclear with a full ban".

So now I can easily point to the continued existence of outright neo-nazism, white supremacy, civil war idealism, violent right-wing rhetoric, terrorism support, and other radical examples of "normal conservative dialogue" on reddit and easily claim that neo-nazis terrorists are "well catered to by the administration" by virtue of the fact that they exist at all and are not banned.
