The Starcraft community requested subscription content for years during the hots years. The popular reasoning was that the game needed refreshing and updating but that a company can’t afford to do it without incentives - and the ongoing revenue would incentivize them to keep the game in great shape.

Then again, you can’t use subscription software at all after the company completely moves on either - no windows 95 compatibility mode to keep using your expensive desktop applications. So you still end up with unusable software eventually - longer peak but a shorter life for more cost

The fundamental problem is how difficult and expensive it is to make software and maintain it year after year
