Although I have some sympathy with this view, you have to accept the general public don't and aren't likely to change their minds. In which case I would suggest it might make more sense to design routers such that they're forced to change from the default password the first time they use it. And frankly the things are already connected to the internet so they may as well do automatic firmware updates. Like an Amazon Fire or Win 10.
In short it's easier to avoid accidents if you design systems that work with human behaviour rather than hoping humans will change.
