When you say "Artificial range limit", are you talking about the buffer? I think all manufacturers have buffers they utilize to allow a long battery life. My understanding is that running EV batteries down to absolutely zero charge is a terrible thing to do to them, as is rapidly charging them to the top. That's also one of the reasons they don't want us charging these things above ~75% on any given day, unless we know we'll be using it for a long haul once we pull the plug.Tesla has temporarily unlocked additional range for emergencies before, like escaping California wildfires or hurricane evacuation zones. But those look like they had the artificial range limit before unlocking also.

Running them to zero is an easy way to degrade and shorten their life. Costly for all, especially if you're the one warranting it to 8 yrs/175k miles. Letting someone dip into that buffer temporarily in an emergency is a great way to save the battery and its owner (and the car), but only if the manufacturer restores the buffer and keeps the battery in it's desired use range.
In this case, I believe RJ was saying if a vehicle exhibits that it's being appropriately charged, used, and maintained, and shows signs of little degradation, the company can "unlock" a greater portion of it's total range via OTA. While we didn't talk about it, I'm assuming that before the warranty is up, they could re-engage the original range to protect the battery, should use/abuse patterns warrant such actions.
