I'm actually wondering if GUN hadn't found a way to dismantle the Eclipse Cannon after that Black Arm debacle. In my mind the Eggman Empire game pretty much ends in a manner similar to Robotnik's Operation Endgame which basically dealt with Robotnik and his spy portraying Sonic as the murderer of his love interest who turned out to be in a coma in the end, leaving the Resistance headquarters defenseless and open to occupation before tested upon with an experimental weapon that erases people atom by atom, the headquarters is left stuck in a time zone from the weapon's firing because Robotnik's second in command altered its function to affect only Robotnik just before the weapon blows up and it's explosion reaches the command center where Robotnik and Sonic are fighting. More than ten issues later or so, mysterious satellites start causing changes which are later revealed to be the doing of the future Eggman. My guess Shadow is both a GUN agent and, like Knuckles, guardian of Space Colony ARK. GUN perhaps have ARK monitored and if Shadow is anything messing about up there he will go up and deal with it personally.

Plus while almost every Sonic game have Chaos Emeralds they're not something you can just buy online so whenever GUN decides to dismantle the Eclipse Cannon or not, it's useless without the Chaos Emeralds.

Also Dr. Eggman has constructed weapons similar to the Eclipse Cannon before, such as the Master Emerald powered laser built into the Kyodai Eggman Robo. Gerald Robotnik was perhaps better at harnessing chaos energy than his grandson was and Eggman could perhaps throw together a doomsday weapon if he wanted too.

Also Dr. Robotnik doesn't want to destroy the very planet he wants to conquer either.
