Well, let's see:
Their kids are 5 and 2. Their parents are doing this for a single year. Somehow, I think that between the ages of 3 and 18 they'll be able to pick up the skills they need.
Even should they decide to do this permanently, there's no reason to think that the parents are going to ban their children from using computers. They will attend school, and socialize with their friends. Hard as it may be for someone on Slashdot to believe, being connected to the internet all the time is not universal. Not even in the United States. There are many, many households that have no or limited access to computers at home.
Finally, there are certain groups that forego technology for various reasons; sometimes religious, sometimes otherwise. It turns out that children from these cultures do just fine. They have lots of opportunities open to them, and if they choose they can learn skills that they might have missed out on at a later point. This is nothing unique to technology -- there are lots of skills that can be invaluable in today's society that most people don't have.
No. It's not abuse. It's a parenting choice, and I'll bet that their children are going to be better off than the kids whose parents think that giving them a cell phone and a television is all they need to do. The fact that the parents are making this decision tells me that they are actually involved in the lives of their children, which is far more important than any gadget.
