For a short while, I worked at one of Samsung subsidiaries on their TV firmware, mostly fixing Linux kernel bugs introduced by the product teams cannibalizing upstream features to serve their needs (including intentionally disabling reasonable kernel security measures that happened to be in their way). I've seen things, both technical and organizational, that led me to pledge never to give my money to that company, or have their devices connected to networks I care about. I don't trust any of it, if not due to evil intent, but just incompetence.
