ZFS will let you setup a RAID like set of small volumes which mirror one larger volume, it takes some setup, but that’s the most “elegant” solution in that once it’s configured you only need to touch it when you add a volume to the system and it’s just a mounted filesystem that you use.
Does not solve the off-site problem, one fire and it’s all gone.
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.
