ICML Author Removal [D]

PhD student. Need advice.

After the ICML abstract deadline, industry coauthors asked to be removed, they missed their employer's internal approval window. They had contributed (discussions and written feedback) but I hadn't explicitly asked before adding them.

January: wrote to PC chairs, got written confirmation from all coauthors, got explicit written approval. Chairs said they'd implement.

Never happened. Paper accepted four months later with original author list. At camera-ready we followed up. Chairs reversed: blanket policy, no exceptions, keep the list or withdraw.

What do you think about this situation? I don't want to withdraw my paper, given that Neurips deadline has passed. What is most likely to happen, and any advice?

Thanks for the help!
