I'm looking for this game at most digital download retailers and it's not for sale. GOG could you please get this game from Activision's back catalog?

Oh no, its starting again.

Anything built upon an ongoing licensed franchise, like Star Trek or even Mechwarrior, is probably several times more difficult to acquire than an ordinary game. Look how hard it's been for GOG to acquire non-franchise games that changed hands a couple times.
