Why do so many devices need babysitters?

from here and here

It's bad enough expecting people to update their ever increasing list of devices, but now you have to actively monitor them too? I don't know about you but I've already got a full time job, I don't need another, especially if it's unpaid. I understand that routers are targets, but there's got to be a better way to mitigate the threat than expecting home users to be vigilant about a device they normally don't even interact with.
