It will be removed from sale on 13 of December, but everyone who already bought it will continue to be able to download it from GOG indefinitely. Furthermore, GOG has stated their commitment to ensure the game remains compatible with newer computer and operating systems. That’s what the preservation project mentioned in the post is about.
I don’t think so. On my screen I see that post I responded to said this:
The game will be removed on 13. December?
So in my post I tried to explain that the games will still be available to download from GOG, but it will no longer be purchasable. Different people mean different things when they say “removed from GOG”, so I thought this was good to clarify.
It wasn’t really a question in that sense. What I meant by that sentence is that the game is already planned to be removed (from sale), so Blizzard suing GOG wouldn’t make much sense. However that doesn’t mean that GOG/Blizzard can just take the game away from those who already purchased it.
