My personal idea is that Starlink is built for automated high speed stock trading across the oceans, because it reduces round-trip latency by some ten milliseconds. Light is much faster in vacuum, almost lightspeed, then in fiber. In fiber the speed of light is around 68% of light speed in vaccum. Giving "Internet to everybody" is just a marketing trick. People who maybe could need internet for social reasons cannot afford Starlink, that is for sure.
