Not sure about the history behind the sounds in the remake, but I don’t think there was anything nefarious about the coincidence. Using stock audio was and still is very common. There are many sound effects from the original StarCraft – such as Terran buildings lifting off or Terran Academy active sound – that I hear in other games and movies, for example.
I still hear sounds from Doom in many modern movies. If I remember right id software was able to open source everything about Doom except the sound effects due to licensing.
