A powerful move would be for Apple to continue renting the space, but close the store and place posters in the windows explaining exactly why they've left, and why things needs to change. Might light a fire under local politicians.
This would accomplish none of Apple's objectives, since they would remain subject to the jurisdiction of that federal district and the local politicians have no say over a federal judiciary appointment.
Congress is theoretically supposed to act as a check on the judiciary, at least to the extent they appoint the judges in the first place. It's reasonable to encourage the constituents to provide feedback to their legislators.
