It's cheating in what way? The developer understands the limits of their hardware, they make choices in engine development and in art to maximize their resources to achieve the most visually pleasing scenes they can.
The difference between someone who actually understands the technology behind all of this, and individuals like you, is that they know the challenges and difficulties presented by dynamic lighting. Those people wouldn't "scoff" at baked lighting, in fact they would be significantly more peeved would said developer actually shoot for dynamic lighting while achieving sub par results (looks at Skyrim).
No, it's not that anyone ran over my dog. It's that I understand the difference between someone who is realistic, and understands the technology (and limitations), and someone who is attempting to devalue the art and work of a development team because it's not buzz-wordy enough for them to put on a pedestal.
