No, that we're dealing with cloudflare, with DDoS protection, is the point here. If you want to run a forum where you ban speech that you feel silences people, that's great, but if you want to deny DDoS protection to other forums that don't have this rule, or don't enforce it to your satisfaction, that's very different.

No we really can't set this aside. Removing DDoS protection directly makes it impossible to run any unpopular website. "Harassment campaign" is a vague term, that can be used (and arguably in this case is used) for any kind of persistent criticism, ridicule, outrage, doxxing - I see harassment campaigns on twitter every day.
This is setting aside the mechanism of the censorship -- removing DDOS protection versus a harassment campaign -- the social or other merit or the speech censored, etc.
Kiwi Farms is a particular clear case to illustrate this point.
