Nothing is stopping existing owners from downloading the offline installer backups, but existing owners will still have access to their games through GOG regardless. Delisting just means that the games will no longer be purchasable, so if there’s a game you want to “own”, as long as you buy it before it’s delisted, it will remain accessible to you for the foreseeable future.

Trader Joe’s has been owned by Aldi* since 1979. The fact that they managed to maintain the image of a wholesome company as long as they have is astounding.

(there are actually two different Aldi companies from Germany, owned by two brothers who split from the original company to make Aldi Nord (North) and Aldi Sud (South), that go by different names depending on the country they’re in. Aldi Nord is Trader Joe’s in the US, and Aldi Sud just goes by Aldi in the US)
