Alexa, Google Home, Nest, Ring, Apple iHome, all smart TVs newer than 2016 and all PCs running Windows 10 1903 or later are on my banned devices list because of the privacy risks they present. (iOS and Android devices are admissible as long as their digital assistants are turned off, and I may add stock Android ROMs to the list and only allow Replicant, LineageOS, etc.) I've already notified my girlfriend of the list, so if/when we make a home together, she knows not to bring anything on it into the home. I'm also training her in how to use Ubuntu and KDE for small-scale productivity.
