> I don't think they are really delaying anything, when the major US automakers are all in on EV's its a lost cause.

I largely agree -- EVs started getting mainstream when batteries started getting cheap. No amount of online astroturfing is going to change the fact that EVs will be cheaper than ICEs in most major markets within a few years (source), or the fact that wind and especially solar are increasingly cheaper than fossil fuel power generation.

The economic forces propelling our transition to clean energy are almost inevitable at this point.

Their delaying tactics -- doomism and hopelessness -- are causing significant psychological distress to vast numbers of people, especially young people. As a result, even if their propaganda is not causing any delay in the energy transition it's still worth combatting for the mental health benefits alone.
