Rebroadcasting a message, regardless of whether or not the opposite message has equal access, is still tacit support for that message, or at least a lack of desire to get involved.

Cloudflare has decided that, for the most part, they won't get involved, but that there are some things that do actually cross the line (a line they are perfectly free to define for themselves), and they refuse to rebroadcast.

If you don't like that, don't support CF with your business. Otherwise, I'm not sure what horse you have in this race.
