“Big oil” is not demonic it is your God as much as it is everyone’s God that uses electricity and all the things you have that are only possible through oil. You are likely not even remotely aware of just how many things you have and do that are only possible because of oil.
Hint: it’s basically 100% of things you have and do. Even your minor deities, Renewable Energy are all a creation and possible due to your God, Big Oil.
How about these companies go from "fuck your democracy lol" to "okay this is bad, this is how we can attempt to fix it". They are among the richest corporations humanity has ever seen.
The dependence on oil is physically plausible, the constant political or public subversion is not.
Is there a rule that you get to be an asshole as long as your products are useful?
When people demonize "Big Oil" they don't mean the product. They mean how the people who run it behave.
