I wouldn't call it laziness. Network setup is something most people just pay their ISP to take care of. It's a commodity service. They don't care how the bits get from here to there, they just want to check their email and go on Facebook.
How many people do you know who, say, do their own water softener maintenance? Is that plumbing illiteracy/laziness, or is it a sign that people are willing to pay for service that frees their time and attention for more productive things?
Except these are self-installs. If it was something their ISP took care of, it would more than likely have a password. So yeah, if I did my own plumbing in a half-assed fashion, I should pay the consequences.
If these politicians and prosecutors cared one bit about helping people, they'd regulate the aftermarket wireless router industry to have passwords by default. Or have the FCC change the rules on usage of the ISM band. Instead, they're just posturing for career advancement and media attention.
