99% of notification requests being blocked is not the same as 99% of users blocking notifications. If every user visits 100 sites and accepts notifications from one of them, then 100% of users actually want notifications despite 99% of requests being denied.

I'm not defending stupid notification popups from some website you'll only ever visit once. Those are annoying. I'm saying you can't tell what users want unless you specifically measure exactly that. Maybe you're right and 99% of users don't want notifications, but that's not what your cited numbers show. You're drawing a conclusion from the data that isn't there.
