That's a typical case of hysteria (correct word ?) caused by lack of information.
I guess a lot of people die in their sleep, but if you hear "Another person died while sleeping - it's the 100th case this year" ,would you believe that sleeping is deadly ? Probably not because you know that people sleep 6-8 hours a day.
Let's say the typical bnet player lives in a country with an average lifetime of 75 years. 75 years=27000 days. Bnet gives us these nice statistics about how many people play at the moment, and lets say the daily average is 50,000 all the time per realm (it's more, but let's be conservative). That means that each day we have 250,000 days of playing games on bnet alone which is the lifetime of 10 persons. The typical player is perhaps 15-30 years old. This is the time of life where the chance of dying is the least. Let's assume that 5% of all people die when being 15-30 years old and let's furtherly assume that only 10% of these deaths can occur at all while playing computer games (the typical cause of death is suicide, an accident or a lethal disease or something else during which you don't play computer games). This means that once per 20 days a person can be expected to die while playing in bnet - just in bnet ! Perhaps only 5% of all computer gamers play internet games on bnet.
I guess that computer games prevent many 15-30 year old persons from the top causes of death in that age category: Suicide and accidents. It's not easy to kill yourself or get killed by a car or something while sitting in a chair and being busy with moving your hands and eyes. And as you have fun while doing it, you can't even consider it a waste of time
