If we didn't buy it...
It's easy to paint the oil companies as totally bad businesses and should be shut down, but a few things to consider:
1) If we, the public, stopped our demand for carbon fuels and accepted there's be no air travel, very little shipping, reduced public transport and gave up teh majority of cars and driving, they would cut production.
2) If we, the public, are prepared to forego most use of plastics (which would have a profound effect on most areas of life, especially in the west), they would cut yet more production (and most would close down). Of course, most of the PPE and supplies we currently need to combat the coronavirus come from oil.
3) The companies we know in the west (Shell, BP, ExxonMobil, etc) are big players but are competing with other big players across the globe. Aramco is bigger than any of these, for example. World production would still continue if the UK/US majors went out of business; the impact on the UK/US would be that we would have no control over production and little influence on supply - not a problem if we roll out lifestyle back 150 years, of course.
Many years ago, I remember a Greenpeace protest outside a BP office, where the protesters erected solar panels and shouted that BP should produce them - somebody quietly pointed out that BP did produce them (including the ones Greenpeace had) and that BP, at the time, was one of the biggest investors in developing solar energy. They would move totally out of oil if there was a viable alternative to it in the current world.
Yes, an unpopular view. We must drastically reduce our carbon footprint; we must be more careful about our use and disposal of plastics. But it's a WE, not just THEM. And the IT industry is a heavy user of oil products...
