It is pretty easy to distinguish DRM from net-enabled features. You simply need to ask "Could the feature exist without an internet connection?" You claim that users will conflate the two regardless, but I doubt this.

Imagine an alternate dimension in which StarCraft shipped with LAN support but never supported online play over Battle.net. The StarCraft community would be based on gamer-oriented VPNs, and would likely be about as healthy as it has become in our dimension. If, when StarCraft II was announced, players learned that LAN play would still be supported, but play over Battle.net had been added, I don't think very many people would complain that the product had been deliberately crippled.

In our world, StarCraft supported LAN play and Battle.net play, while StarCraft II does not support any type of multiplayer other than over Battle.net. Battle.net play has resulted in half-second latency for all players and several days of downtime since release. Additionally, it is known that a "Professional" version of StarCraft II exists that supports LAN play - the feature has simply been removed from the retail version.

I think it is pretty clear which of these is a feature and which is not.
