Well, Toyota's claims about batteries are intended to convince people not to buy EVs yet. They're going to be SO much better real soon now so just buy another Toyota gas car and think about EVs next time.
It's just another flavour of the anti-EV FUD Toyota has been spewing for a decade now. They're also saying that hydrogen is the future and that gas will always be 70%+ of the car market, so you have your choice of anti-EV FUD. Consistency doesn't matter when you're running a disinformation campaign.
