Like I agree with your general point but this has nothing to do with online games licensing besides its being pulled from digital store fronts. Brick and mortar stores can have product recalls as well and this would likely be in that same category of problem (its a bit weird with preowned games since publishers were already given their cut) so they can continue to sell those but a brand "new" copy may have suffered a similar fate but we have to remember Spec Ops the Line is from the 360 era so I doubt there would even been many "new" copies around. Also I can't fault publishers from just "deleting" a game from existence because spending thousands for merely upkeeping the licenses for a game they realistically haven't sold in major volumes for nearly half a decade (at minimum) seems a tad bit unreasonable. Most music labels likely aren't even going to sell a perpetual license as well, so its a can of worms of people wanting to get their cut.
