Also important to cut out caffeine if you are stopping nicotine. And understand that caffeine can be a trigger, nicotine accelerate caffeine metabolism (cuts the edge) which is why the coffee-drinking cigarette smoking trope exists. Caff and Nick are the best of friends.
WUT? Apple is very focused on privacy and the idea that a user can’t mute or install Adblock is… weird. Safari has good ad-blocking options as well as built-in anti-tracking features to protect users, applications can’t usually prevent the system from muting content and Apple doesn’t really sell ads outside of the App Store.
If you want to worry about that stuff I’d suggest focusing on the Meta VR goggles or god forbid Google starts making goggles, both of those companies survive on ad revenue and have an incentive to enshitify their experience in ways that the Apple we know today would never do. Of course companies can change over time, but the ethic at Apple is to only make products they feel comfortable with their families using.
