Honestly always online DRM is illegal. You cannot provide a good a service. All these companies who are planting these time bombs into software and devices need to be handed a big FU and realize that they are creating the piracy they claim to protect against.
I like Valve, but I don't like them enough to believe they won't close my account on a whim for no reason one day.
I would like to see further development but I always had a sneaking suspicion that its life was limited due to the fact that ARC does not come from Intel's fabs either. Like lunar lake, Arc is also made at TSMC.
