Normally, I'm 100% on the pedestrian's side, and I think drivers bear the responsibility in basically all urban traffic situation. However, after visiting San Francisco, I can see why it's a bit different. Those hills severely limit visibility on so many of those crosswalks, and if you're driving up one of them, and the sun is in your eyes, I don't know how you would approach an intersection safely. After less than a week in that city, I realized that pedestrians really do have to cross responsibly (and also I would never, ever drive there).

That being said, I've never seen less people jay walking in an American city than I did in San Francisco. Also, all of the measures laid out in this article seem like good, common sense ideas. If drivers think that the pedestrians need to be more responsible, fine, but that's no reason to demand the rollback of potentially lifesaving safety measures.
