They kept them broken in fear that Homeworld would detect them being active again and giving away the fact that there were crystal gems still alive on Earth. It would have been incredibly risky for Rose to pick up Spinel with the glaxy warp pads since the signs of their activity would probably be detected in Homeworld even if Garnet broke them afterwards. That could start another war with Homerworld that the Crystal Gems wouldn't even have a chance to win.
