the point being that instead of there being a kind of commission to create a schema, there are a whole bunch of different whitelists. so if your religion objects to the existence of mangoes, then you can subscribe to a mango-free internet filter.

and instead of burdening the isp the publisher of mango sorbet recipes with ticking off all the right schema boxes, this can all be enforced at the consumer.

all the rest of these approaches kind of assume that there is 'reasonable' and 'unreasonable' content, and that we all mostly agree on the difference. which I think is fundamentally fallacious. do you really think we can agree, as a species, what PG-13 should mean for the entire internet?
