These are companies with some of the largest revenues and stock market caps in the world (that you coincidentally think are evil and have labeled as "big oil") and they have all of a sudden enter a market space you support. Which do you think is more likely, (A) Exxon-Mobil has suddenly developed a progressive mindset and "saw the writing on the wall," or (B) they've done market research and see people like you as a vast untapped market of people willing to pay premium prices for alternative energy consumer products as a means of virtue signaling, and now indeed are successfully lobbying the government to mandate their purchase) and they want in on that gravy train? These companies believe in alternative energy as much as Halliburton believed in "bringing democracy to the Middle East" during the Iraq War, which is not at all except for convincing a government to keep on spending money that will go into their pockets while praising your "wisdom" in supporting such an obviously good strategy.
Or the simpler answer is that they are energy companies that operate on an infinite time horizon and rightly conclude that their current investments have a limited future so they need to diversify. It has nothing to do with some made up ‘progressive mindset’, it’s just common business sense.
The pro-choice side has already argued a zero value for the "yet to be born," so that's not a valid argument in favor of solar now.
Now you’re being silly again. First, what you said is false and second, even if it were true pro-choice positions and pro-solar positions have nothing to do with each other. Total fail.
