Meta has a history of churning out MVPs and doubling down on what works. Launching with a desktop client, EU, etc are in direct opposition to a lean MVP. Meta definitely has some missteps but not sure this is one.

Tying in to Instagram was what made it resonate with such a large audience vs all the other Twitter clones. Carrying over the social graph was a wise decision imho.

The Starship analogy makes little sense as well. Starship is not an MVP and well on track to continue to push forward the state of the art of rocket engineering.
