Owners can join and leave - you see that frequently whenever a league membership looks stagnant.
Owners cannot leave once the league max is set (12 teams or whatever the set parameter), but up until the point that a league is filled, owners can join and drop as much as they'd like.

I assume that you are referring to a league that is NOT a 2015 League. Many owners are likely holding back in joining new leagues anticipating the release of the new 2015 set.
