I feel you contradicted yourself here. In one way you excuse it, but you also claim users should know better. When it comes to having a strong password, I feel this is where it's acceptable to place blame. When, for example, they went to their favorite website which has a malicious ad that takes advantage of the latest exploit. Can they really be blamed? Average end users expect their smart thermostat to give them capabilities advertised. Some can't even imagine that it's basically a small computer.
> that violate the contract you signed with your ISP
How many people really read these agreements? It's assumed that if your computer works it's in spec. Whatever arbitrary clause they came up with to allow them to legally track your every move is a different conversation.
I won't divulge into throwing analogies back and forth. I'll just say this, I know plenty of Dr's, people who are much smarter than me that don't know a thing about networking. They're running their own practice and stay concerned about being up to date and not getting sued. That's their job. Building software that is easy enough to use while keeping people secure is ours. There's no excuse, it's hard and it's yet another aspect programmers need to learn. But it rests on our shoulders.
