I voted no, for a few reasons that have a lot to do with having hindsight as 20/20 after my kid marched 7 seasons.
For many reasons, when he was still marching, this was the ONE corps that was a no from us parents for him to march at, particularly while he was underage, due to many things we'd heard from verifiable sources (staff, kids who marched there) that were for sure just not a good fit for my kiddo. Not every corps is for every kid.
There were other personal reasons as well that yes, did have to do with the leadership of that corps. I won't go into that here, but it seems that my intuition was right.
If I had it to do over and this had happened AND my kiddo were an adult, then no, I don't suppose there'd be anything I could do to stop them from marching there if it were his heart's desire - nor would I want to. As a parent of a minor though, I'd have some concerns over this season for sure, and I think that's fair under the circumstances.
I wish nothing but the very best for the staff and MMs of the Cadets organization and hope they can recover from this swiftly.
