I think you might be mixing up this with the actual Starlink sats, which yeah, def pollution. This is from the second stage reentry and only happens for a few minutes in a specific area. Theoretically, Starship will not do this as both stages are reusable...buuuut I imagine they will end up trashing a few stages on the way to get there.
