There was more time between Cloudflare dropping 8chan and KF than between Cloudflare dropping Stormfront and 8chan. By the (very dubious and limited, but) only metric we have, the rate of Cloudflare's "bad site" removals is slowing, and its a factor of 20 or 30x from monthly like you're claiming.

The sky isn't falling, and the slippery slope is demonstrably not there in this case.
