Normies usually have their updates set to automatic, so they get the updates a soon as they're out.
I count over 9 security updates for iOS 16 [1] as of July 10th, with the rest of the year to go. I feel like as soon as any type of update is released by Apple, I'm inundated with the news from many websites, RSS feeds and the PGP-signed email from Apple with the news [2] [3].
