While this is true in theory, in practice it rarely shows up. If these trucks do deliver a good, simple experience at $25K, others would not be able to just copy it and catch up. It would be easier for any of the big guys to just buy the company.

I agree, but without the complications of a combustion engine, it makes it a lot easier. You can buy ev conversion kits for around $15k, so there's also an "I'll make my own, with blackjack, and hookers" option.
