Knowing HD DVD zealots, they just could not let this go. While they were so happy to point out disc rot on some early Prestige copies, they got bitter when they were alerted to earlier wikipedia descriptions of disc rot on HD DVD first.

Thus, someone just had to add in a comment "Rotting has been a major problem *especially* for Blu-ray discs" to wikipedia. Notice the bolding of blu-ray too, while they hope that people might not notice any mention of HD DVD. It is disappointing to witness this.
