If they're not doing evil work, why all the secrecy? It's not like they're going bankrupt either since, like you mentioned, the demand is not going away

Because people are hipocrites - our stated goals (clean environment, fair business) are different from the actual ones (get a lot of stuff and energy cheaply)

But these shouldn't be in contradiction. Oil and gas will end when they will be unprofitable, priced out by much cheaper renewables. Of course this will result in more and cheaper stuff and energy, boost economic growth rates not suppress them.

It's hard to compete with something that is allowed to externalize the majority of its costs.

Well, regardless of what government does, renewables will eventually price out oil and gas. And the government and the megacorps will be on their side because that way they will be making more money. Not before.

No one is trying to limit renewables just for the sake of it. They are trying to do so because so far renewables don't allow to make much money while oil and gas does. There won't be any reason for the powers that be, to resist them once this situation reverses.

You could say the same about any drug lord.

If your business harms the masses maybe you should overthink your business model.
