I think the saddest part is that Blizzard's reputation alone will continue to let them do whatever they feel like and still be a successful company.
When Ubisoft pulled this, they felt the loss in sales and people not supporting their products as much as before to the point where they stopped with online only DRM. But if Blizzard pulls it, complaints are as far as it gets.
Everyone excuses them. From game reviewers to blind players, because if it is a Blizzard product, it must be worth the money, inconvenience and dissatisfaction to play it.
