Was the original Tesla Roadster made by them using an AC induction motor?
I literally don't know. However, that's where I'd draw the line between who deserves credit. If it was Musk's idea, he deserves it. If it was them, then they do. Because that seems to me to be the major innovation. Also, if stationary storage devices started with them, then I'd argue their long-term plan was probably better than Musk's. However, I don't know who started that either. It just seemed like the long-term plan was to use eco-conscious rich people to finance storage innovations that would make the overall grid much more efficient through stationary solutions.
