The word "become" is the operative verb in my post. Rooting and jailbreaking are not the same thing in common vernacular now.
Go to any pirate IPTV forum or even more common places, and "jailbreak" is the term they use to describe turning on the "allow apps from unknown sources" feature on with a Fire Stick. It's the same as me doing that on an Android phone. I'm not rooting my Android phone by flipping a switch. Jailbreaking is also the term the cable industry uses for this as well. It's just newthink vocab to try and make it sound like something you shouldn't do, because it helps maintain control of the public mindset when it comes to things like pirate video streaming.
"Jailbreaking" an iPhone is different, and we don't need an "official jailbreak" for iOS like the parent commenter (xack) said. We just need to compel them to add the exact same "install apps from unknown sources" feature as Android has.
