When it comes to piggybacking on another company's EVs hardware, Subaru has Toyota, Ford has Rivian (and Volkswagen), and Honda now has General Motors.
Every time I think I might want to get a Honda, they give me a reason to stay away. No GM for me, nor Ford either. Ditto VW.
Of the collaborations mentioned in the article, IMHO the Toyota/Subaru one will produce the best vehicles.
Of course there is a first time for everything .
