I was thinking about desktops, where the fan would be physically plugged into a fan controller instead of into the motherboard. Not sure what that would look like with a laptop.
I was mainly asking because some of those fan controllers default to full on when the usb connection is absent, and Windows doesn’t enable all usb connections until after the user logs into the system.

For single player games, I absolutely agree. If you’re going to stop supporting the game, send out one last patch turning off any always online DRM and let people keep playing their game.
For multiplayer games, it seems like it’s a bit more complicated. Who should be shouldering the cost to keep the game servers alive?

Depending on how much time your server spends with those CPUs actually under load, newer processors may not really help your energy bills. Even old processors idle at single digits wattages. Most of the idle power consumption (where most home servers spend 99% of their time) on the server will be coming from fans, RAM, and storage.
The problem is, there’s no real good way to “listen to consumers” other than to ask retailers what is actually selling.
Online chatter is notoriously unreliable, not just in games, but in a lot of sectors. Car enthusiasts go on and on about what nostalgic car they want, but when auto manufacturers try to sell some version of that, there’s a million excuses why they bought Generic SUV #472B instead. Music artists have millions of followers on Twitter and Instagram, but can’t sell albums and have to cancel tours due to lack of ticket sales.
Also, at one time, it might actually be true that very few people wanted that style of game. Trends and preferences are constantly changing.
