Can't this same principle be applied on a smaller scale?
Yes, but are you willing to (roughly) double your internet bill to get that redundancy? If you are like most people, probably not.
It feels like you're trying to push her into a career she doesn't really want to be in. If I was you, I'd respect her wishes and instead support her while she finds something she's passionate about.
Let's be honest, writing enterprise Java is enough to kill anyone's passion. That stuff sucks your soul out until you make it to architect level (then you spend your time sucking other people's soul out).
She should find a job that interests her more (while lets be honest, work is called work because it's not fun). Then, if that job happens to be embedded programming, she get a raspberry pi and work with it for a while. After a couple months she should be more than proficient enough to find a job in embedded.
In any case look through job postings until she finds something interesting. Once again, work is generally not interesting.
This is getting tiring, and along with "walled garden", it is really stale and worn out as an argument.
If you could install your own browser on iOS, then browsers wouldn't be a problem. Because of the walled garden, you can't.
"Walled garden" isn't a tired argument against iOS, it is a very serious problem, but fanboys would rather ignore it or call it 'worn out.' In reality it sucks and there's no need for it, and plenty of reasons to not have it.
in cases where the vulnerability is actively being exploited, disclosing immediately, publicly and completely is always in the public interest.
Usually an admin can solve the problem with a firewall, or by temporarily disabling a feature, or something similar. Don't leave people open to attack.
