That's certainly a way to view the data, but it's a way that ignores the trajectory of the technology and sets up The Big Three for complete failure.
The Big Three have not figured out how to make compelling EVs, without a doubt, but it's not the technology that's the problem, it's the leadership's product choices and failure of implementation.
Meaning that the entire industry will be pushed farther and farther behind in the race, only to be completely disrupted.
This will happen far slower than the transition from Palm to iOS-style phones, because the lifetime of cars is far longer than phones and are far larger investments, but the trend is inevitable. EVs are superior on so many different fronts that there's ~0 chance that gas and diesel engines persist except for a tiny fraction of future market share.
US manufacturers are trying to delay the transition as long as possible, which only ensures their own doom.
It's not just the Big Three, it's a boat anchor of the Big Three + Tier 1/2/3 suppliers. Tesla probably most vertically integrated of any, therefor most likely able to survive a major pivot.
