Good move from my perspective. The user isn't opting in to participate in this mining so it's ethical for Cloudflare to protect the user.

  Opt-in mining as a form of micropayment for content might be interesting, though. But the key term there is opt-in.

  > According to Cloudflare, unannounced miners are considered malware. This suggests that Cloudflare might still allow "announced" miners, even if they aren't opt-in.

    If they're well enough announced, you opt in by leaving the tab open. You can opt-out immediately by leaving.

      Opt-in is clicking "opt-in" button.
