I think the executives at these companies have long since identified that EVs are a far more fundamental existential challenge than people normally understand. The reason I think so is that Internal Combustion Engines are the primary barrier to entry into the car market. In an all electric world they are once again open to competition from startups who can source the same commodity motors, batteries, controllers, and the like. The barriers to entry drop and it becomes a brand new world of competition from all sides. The only major stumbling block being regulatory (crash testing, etc...). Nobody in the industry wants that, so the best solution is to fight the EV adoption as long as they can. Had Tesla not been a company they would still be dragging their heels with compliance cars to this day.
Of course countries without existing ICE manufacturers to protect, like China, are free to take control of the EV market and dominate the auto industry in the coming decades. An existential crisis for legacy automakers.
