I would say that any software that has 4 billion MAU quite reasonably can be classified as "the world runs on it"-tier software. If I had to guess, what I think you're doing is you're letting your opinion about the morality of FAANG-like software (ads, tracking, mal-influencing, etc.) be a judge on it's utility. FAANG-like software is like fossil fuels. Fossil fuels, like much of FAANG-software, have many immoral aspects, yet they have utility to the point of "the world runs on it". Google, DDG etc. connected the internet. Facebook, twitter etc. connected people on the internet. I'de say that's something of a big deal.
