If the case for the battery was objectively better, oil companies would pull a phillip morris and buy out their antithesis to profit on both ends. The fact that they are doubling down on hydrogen itself I think its really interesting. To me, this shows that perhaps there is a true advantage, and also a high enough barrier to entry where only these oil companies at the scale they already exist can reap the most benefit. Its hard to know where the truth actually lies due to our propaganda/media environment, but I think these actions at least do inform of it a little.
