"Free speech" is the wrong framing! "Free speech" is about the government suppressing or punishing you for what you say, and we aren't the government. Any online site that accepts user-generated content (which is the fancy term for "the stuff y'all post" as opposed to "the stuff the site itself posts") has to set forth content policies that govern what their users can post, because without those policies (and active enforcement of them) a site will be unusable in days, if not hours, because it will be overrun with spam, child sex abuse material, and a thousand other categories of things that make a service impossible to use and create legal liability. Like every other site out there, we have content policies that govern what people are and aren't allowed to post, and we will (and do) remove content that's reported to us that violates those policies.

We do our best to draw those content policies as leniently as possible, and we do allow material that other sites might not -- one of the benefits of being entirely user-supported is that we don't have to worry about restricting user content only to things that advertisers find acceptable, for instance. But like every other site on the internet, we do have content policies, and we do enforce them through various means, from requiring removal of a single post or comment all the way to closing a person's account and not letting them create a new one. For us not to do so would be irresponsible, and it's that very irresponsibility that has led us to conclude we can no longer do business with Cloudflare. A service that says they regret denying service to a site containing child sex abuse material is a service we cannot continue to patronize.
