Sure. Neither you nor I were in the room, and the evidence is that the committee that was in the room evaluated those plans and it seemed more unlikely to meet the goals.
Given Musk's track record, it is very reasonable to treat any timeline with a shipload of salt. He literally took $thousands from thousands of customers for Full-Self-Driving upgrades that were to transform their Teslas into self-driving Uber/Lyft goldmines by 2021, not 2022, not 2023, no... oops, recall 2 million yesterday because of safety failures in "autopilot" that isn't. Even with the assumption that Starship is not part of the equation, Starlink still is falling down on bandwidth reliability as subscription exceeds capacity.
