We can blame Trump for a lot of things, but not this particular instance. This would have happened before Trump and I doubt Biden had any say in this either. This was either something coming from the FAA or congress (I haven’t read into the history of the move).
One thing I do question is given that some operators didn’t not want to move, that they didn’t opt for a hybrid solution, with some operators in the local location and some in the remote location. At the very least it would have provided some sort of redundancy, since communication lines over a distance would risk becoming a weak point.
