For some people, the possibility of an upgrade is a major reason for staying with an airline and seeking elite status. The possibility of an upgrade has been decreasing and the move to FCM may effectively eliminate the chance. If so, it does not become a reason to jump ship, but it does eliminate a reason to stay. The devaluation of elite status across airlines seems a fair reason to become a free agent.
Allowing upgrades for the price difference between Y and F does not appear to be something anyone can reasonably complain about. Allowing upgrades for TOD is another matter. In addition to the problem of fewer elite upgrades, if one can reliably upgrade to F for less than the fare difference, why buy F in the first place?
