Because you (and others like you) are probably not a substantial source of revenue to Cloudflare. Big companies who are the bulk of Cloudflare's sales (and whom they spend >1.5x on courting than they do on engineering) would rather not be hosted on the same infrastructure that powers hate groups. Not really as a moral thing, but in the same way that e.g. Volkswagen or Samsung or Allianz would rather not advertise on a child pornography website, they'd also rather not host on an infrastructure provider who provide services to a forum whose members try to drive people to commit suicide, make bomb threats, fake calls to counterterrorism hotlines and generally espouse _extreme_ right ideology.
