I'm aware that Business is routinely oversold by the number of First Class seats still available, but what I appear to be seeing goes way beyond that. In this case they've stopped selling FC seats (F0) and all six FC seats are assigned, so there's no overflow except bumping people (upgrades, of course).

While I've lost my upgraded seat on very rare occasions for equipment changes, IRROPS, or an unanticipated celebrity, I've never felt that it was because of a deliberate oversell. Perhaps I'm naive, but say it ain't so!
