If somebody is "launching" (as in public launch) an "MVP" then they're doing it wrong in the first place. You don't normally take an MVP and put it out there for the entire world. You release it to a (carefully?) selected subset of users, that you've pre-identified somehow, whom you expect to get validated learning from.

If somebody builds a crappy app, pushes it to the world, and slaps an "MVP" label on it, they haven't built an MVP and they're not really following the lean startup / customer development process.
