Well it seems it was more to do with sanctions, if the open letter from one of the chopped developers is to be believed. In which case, I think the right thing is to move the names to contributors (they did still contribute), remove them from maintainers (some maintainers are actually paid by the foundation, I mean not a lot, but some are paid).

I still find it all a little odd. But likely there was a bit of a prod from somewhere higher as to how sanctions should be followed.
