End users switching to Cloudflare's DNS endpoint are doing so because they feel the DNS provider is both faster and more secure.
They rightly made the decision NOT to pass on the end user's IP information to the upstream DNS server. I agree with this decision and they are acting in my best interests in doing so. To draw some kind of nefarious intention from this is absurd.
Until Cloudflare are proven to be nefarious actors, I'll continue to use their service.
