This was an embarrassing episode for that company. Matthew Prince said as much. He said something like "I did this because Stormfront claimed that we platform them because we are Nazis. It's bad that I can do this." I thought that was an especially bad look for him personally, like, if he has the presence of mind to dislike that, then he should exercise it to not take the actions he says he dislikes. Around the same time, the company also deplatformed Switter, which was in my view going beyond their legal obligations, and was also extremely disappointing.

Disclosure: I worked at Cloudflare at the time and am generally biased in favor of Cloudflare.
