it maybe comes down to "what have you got to hide"
if you don't keep your banking passwords in clear text in notepad on your desktop what's the hackers target ?
and why bother to hack via all these new things connected to the router, when they could just hack the router instead? - everyday seems to bring another well publicised loophole and how-to for doing that
but back to content, assuming you have secured all of your your logins/passwords then what does that leave?: Surely not your digital books, music, videos etc .There are thousands of dodgy sites offering copies of all of that stuff anyway which are much easier to access - & if its those embarrassing nude selfies well you could just stop taking them
