I don't think Levine had any good feelings towards the Met since his firing.
As for the orchestra, did any musician, let alone as a group, ever speak up for him?(NOT that I believe they should have nor that he shouldn't have been fired.)
I guess my position is that even if none of the Met musicians "spoke up" for Levine in terms of defending him against moral improprieties and/or crimes of which he was accused (and which had been discussed behind the scenes for DECADES), Levine might have willed a large amount to the Met orchestra musicians directly as a way of commemorating and preserving the positive legacy he left in building that orchestra to a world-class ensemble.
