Perhaps the same way that Github works when you host your web page there. I.e. A revocable, limited license, where you retain full ownership, and only grant them permission to host and serve your content + a limited set of other uses, and you dictate external licensing?

Yes, but this is the perfect circle of slop: generate an ai landing page, throw it into cloudflare drop, ai adopts it, start all over again. For genuine, professional content, I would assume, almost no one uses cloudflare drop, as they already have something in place to test and quickly host some page. Moreover, I expect that scammers and phishing campaigns will have a use for it to quickly up some landing page without leaving a large footprint.
It's not like every SaaS wasn't using the same style of landing page before AI.
