Harboring such a pest, typically used in extortion, is just not nice, even if you personally do not directly feel any ill effects.
A lot of those "residential proxy services" work by routing traffic through infected devices. The operators of them just buy "installs" (dirt cheap) from botnet operators, etc.
An infected device on the home network can also be staging for (automated) attacks against other shit on your network. Fun times.
Oh? With what result at the end of all that?
Otherwise this reads like typical "infosec" fearmongering turned up to 11. No different than doomsday preppers.
This all gets bought and sold on black markets, and gets used weeks and months after being stolen. Spam sent covertly from your mail account, mystery charges on your CC, etc. Not pleasant. At the worst case, a full identity theft, then behold a $30k loan taken in your name, for you to repay with interest.
What if a super-volcano erupts tomorrow, do you have enough canned beans?
