As someone who works in this space, the headline is a bit of a stretch. The overlap in the locations of Pokemon Go Player data and any active Drone heavy theaters of war is a tiny sliver (or zero?). The military contractor (Vantar/Maxar) in question basically admits so but just "reserves the right" to use the data which is the political battle line ala Claude and DoD. This is mostly an ideological battle.
As a Pokemon go player, I would say it isn't. There's even a Pokemon exclusive to the middle east region: sandstorm pattern Vivillion. Lots of players there.
Maxar is/was primarily a satellite data company, and to say Pokemon data would add any major value in any of today's active drone deployments with the level of Satellite coverage Maxar already has is a wide stretch.
Moreover, ground forces in the area would need pretty heavy jamming tech in place too for this kind of data to be useful. It's a sliver of a sliver of a sliver situation.
