As much as I understand this is needed it rubs me the wrong way.

The standard looks fine as a distributed protocol until you have to register to pay a rent to Cloudflare, which they say will eventually trickle down into publishers pocket but you know what having a middleman this powerful means to the power dynamics of the market. Publishers have a really bad hand no matter what we do to save them, content as we know it will have to adapt.

Give it a couple more iterations and some MBA will come up with the brilliant idea of introducing an internet toll to humans and selling a content bundle with unlimited access to websites.

Cloudflare is only the first to market with a solution. If this proposal catches on every WAF vendor under the sun will have it implemented before the next sales cycle. Enforcement of this standard will be commoditized down to nothing.

There is just too much spam and it's not clear that is a solvable problem without Cloudflare (or some other similar service). Maybe if they get big enough the incentives to spam will vanish and non Cloudflare sites can exist in peace (at-least until enough people leave Cloudflare that spam become profitable again).
