The problem is that cybersecurity is ridiculous hard problem. The junior to senior developers are just using existing frameworks with poor documentation. Any consumer technology will be beaten to submission. It's the same never-ending war as anti-cheat vs cheat.
Another example: my grandma doesn’t have WiFi, and I bought her an iPhone, but iOS updates can’t be done on 4G, which can only be bypassed by internet-tethering a computer (which she doesn’t have), downloading the full IPSW, and installing it. She was on iOS 14.0 until 2 weeks ago when I fixed it. And with Safari being, according to security researchers, much less secure than Chrome, that makes me shudder. This isn’t an “anecdote” or an edge case, not everyone lives in a developed country and millions are just like my grandma, and Apple’s poor security design leaves her vulnerable for zero good technical reason, where Android wouldn’t. (They just dropped Google Play Services support for Jelly Bean a few months ago, so even an old Android phone would be reasonably secure). Caring about security requires thinking of details like this.
