I had a few instances of OwnCloud and various NAS setups over the years. Then I had a kid and dumped everything into iCloud when I realized I’d no longer have time to keep it all secure/patched. Time cost of these setups is real.
1) could I fail to detect a failure of an auto-update or novel exploit because I’m more busy now?
2) if so, could something very bad happen?
I got two “yes”s. It still annoys me to have everything in iCloud, but I also have local copies so I’m not too stressed about account lock out.
Otherwise to each their own, it wasn’t an easy decision to give up the autonomy, but the risk/reward equation changes when my time became more scarce.
