My guess is that Q wants anons to learn how to use the Ghidra toolkit now in preparation for a future drop that will contain a gift. The gift will be a software program of some sort, perhaps a video game that the deep state used, that can be reverse engineered using the Ghidra toolkit. Upon inspection of the reverse engineered code, anons will make new discoveries.
Recall recently in drop 4105 where Q said "support will always be provided" using [undisclosed methods]. Maybe Ghidra is one of these methods.
