As a musician, yeah, don't agree with this. It'd be great to find a way practical way to get content creators compensated, because with the internet, almost all media is becoming free (or near free), and it's hard to survive.

And, the idea being proposed is a version of what you're talking about (paywall). Not allowing crawlers to scrap your site unless they compensate you is a form of paywall, just for crawlers...

...But, I do agree with one aspect you're saying about greed, Cloudflare is probably being self serving in this. An open standard seems like it'd be a better solution than having one company control content payment.
