I could have admittedly been less crass about it, but my point is that it's more than a little disheartening to see people engage with a basic principle that's as foundational and indisputable to economics as evolution is to biology and still feel the need to label it as tinfoil hat conspiracy.
Yes, oil companies lower prices in response to decreased oil demand, because they think that that will make them more money. This is not meaningfully different than old VHS tapes being cheap, or on the opposite end, someone leaving for a higher paying job after gaining more experience or more specialized skills. Prices are not randomly pulled out of hat; there's a reason that you can't sell an avocado for $10,000, nor can (most) workers charge $10,000 an hour for their time, and that if you instead sell avocados for $0.10 each, you'll have a line of people around the block (and soon be either out of stock or bankrupt).
That aside, if some dry sarcasm is your bar for "being an absolute dick", you must be surrounded by literal angels.
