Many people think their claimed TAM is total fiction, and attempting an actual realistic TAM relies far more heavily on starlink. From morningstar:

Then either the TAM for Starlink is ~20x bigger than reported by SpaceX (I doubt they would downplay themselves in such a way) or the whole SpaceX TAM is ~5x smaller (much more realistic, if not more than that)
