I would have agreed with you a few years ago, but coal producer antipathy toward O&G has increased a lot since fracking unleashed the cheap gas that has been eating their lunch. At the same time gas producers have softened their stance against climate action, calculating (correctly) that in the short-medium term coal-to-gas switching in the name of climate action can send a lot of new natural gas demand their way. As for the long term, either they don't care yet or don't really believe that natural gas and oil will eventually be in line for replacement too.

They simply pretended that they were "cleaner" than coal and gas, which isn't really true:
