The modern pattern in anywhere that allows it is to have dozens of ambiguously labeled toggles for nominally different notification channels, described only by a minimally brief and maximally ambiguous label. All begin as active until the user, in frustration, goes in and exhausts themselves disabling individual options without being sure which one is going to turn off the one single thing they actually want to be notified about.

Then next month, you create a new notification channel for your new promotional messages because too many people opted out of the old channels. You default that new channel to opt in, to make sure the user gets their chance to experience it and share in the delight you mean to share with them.

Presumably, you continue this until you have hundreds of such toggles and presumably some kind of dedicated Toggle Engineering Department that oversees them all. Nextdoor, Meta apps, LinkedIn, and countless others all appear to be competing for the most such toggles.

Though Android does help a little for existing toggles by giving you an 'About 129 notifications per day' blurb below the entry.

After all we wouldn't want the user to miss out on our promotion of 10% off your next refrigerator. They bought a refrigerator from us just 6 months ago, after all!
