I don't think most people realize how huge Mozilla is. Their annual revenue has been flirting breaking a billion dollars for some time now and was ~$500 mil as of 2023 - primarily due to 'partnering' with Google, which was always a bellwether to anybody who cared to see it. Wikimedia has never broken $200 million per year. In other words, it's Mozilla that could buy Wikipedia, not the other way around.
