We're getting a heat pump/air handler system for the house that comes with a wifi hookup. Guess what's not getting hooked up to the wifi. Same with our "smart" TVs; I've set up cheap mini PCs connected to them and have sandboxed them to hell and back. We'll be replacing our garage door openers pretty soon - guess what, I'm sure they'll have wifi and phone apps, not getting installed.

Pretty soon the only thing I'll have on my network is an HP 4L and a loaded handgun next to it in case it makes a suspicious noise...
