> We don't have multiple different type of gasoline We have diesel and gasoline at least. However the key difference ethere is somewhat different: We have independent supply lines, starting at different oil fields, going through different refineries, into different distribution networks, which ensures that there is some competition (even oligopolic is better than plain monopoly) and supply chain attacks on one vendor don't havoc the complete supply chain. For a practical example: Countries were able to massively reduce the dependance on Russian gas and oil recently. If Google however decides to havoc chromium development all dependants have trouble.
