No way it meets "unlimited Supercharging." Grammatically, it meets "free Supercharging," but we can all agree that's a shift from the original intent.400kw is like 5 full chargesand 1,300 miles, there's no way they can claim Free Unlimited Supercharging meant 1,300 miles a year whereas an average car puts on like 15,000 a year...
I personally remember a time when their website said that any owner of a legacy Model S or X who traded in their car would get free Supercharging for life. I never took a screen shot, and it's possible my memory is off, but I recall being elated to see that.
