The server can, and often does, shut down when the business is still around. Nexon is still around, but Warhaven is going away. Ubisoft is still around, but you can't play The Crew anymore starting in April. I know that there are limited time and resources involved in any project, but I also know they should have spent those resources on making a product that will last, especially when their competitors in V Rising or Titan Quest II managed to do so. This is forced obsolescence, whether they intended it to be or not, but they almost surely intended it to be.
