The dancers who sent the open letter whine about "potential detriment to [their] careers".
They don't have careers. They didn't have one (each) before and they don't now.
It is not yet possible to force an individual to employ another individual, and I am reasonably sure that no individual wants to employ in a team anyone who has proved him- her- or whatever-self incapable of working as part of a team. Why would a dance organiser take that risk? He or she or whatever also has a career to worry about -- an actual career rather than an aspiration to have one.
The reputation these foolish young creatures have gained for themselves is not going to wash off with soap and water.
It's telling, I feel, that after one did resign, another more experienced dancer (possibly one with a real career rather than the wistful notion of one) was able to take on that part after two days' rehearsal.
