Which is it? Are they responsible, or are they not?
The fact that it's free does not absolve them of any moral obligations. (Besides which, it's not "free," it's ad-supported. You're implying that they should get points for their selflessness in providing this service to the world, but that's not what they're doing.)

Why make assumptions when there's information readily available? Look at picture in the article. This was a narrow gap in an unlit, unpainted road in the forest, at night, in the rain. The guardrails were still up. Even if you were tightly focused on the road and driving at a reasonable speed, it could easily look like nothing more than a dark spot in a dark road.
The greatest blame probably ought to fall on the local authorities that didn't properly block off the road. But, again, there doesn't have to be just one bad guy.
