That's not my point. Cloudflare is blocking all unregistered automation as "AI Training" by default. My guess is we will see almost no one changing that default, as opposed to the inverse where only some sites will be forced to enable the blocks. Opt-out is a very bad model for things like this because it heavily hurts users (especially assistive users) while most websites won't have a strong enough opinion to even consider it.

I don't think we will see Cloudflare enabling an "age assurance" requirement by default. I feel like I could trust them slightly more than a site operator, depending on how it's performed, but I also feel like it would be very easy for them to do much, much worse than any site operator, due to the inherent power of being a GAA.
