Mmm, so glad I live anywhere but there. Imagine if they tried to do that in America. Oh man, riots man. Riots. Sucks that they lost their son. That's deeply terrible, it really is. Nothing can justify their actions. Nothing at all. No addiction deserves death from those trying to "help" them. That's just bullshit.
However, you can't really blame people for getting addicted to something like the "internet". Different factors key into addictions, especially an internet addiction. Technology has made almost all the information we need right at our fingertips. Instead of going to a library and looking for all the information we needed or wanted, we can just go to Google. Social face-to-face interaction isn't needed behind a computer screen. We can hide all of imperfections and polish ourselves with some online persona that people either revere or detest. If they wanted to keep people from behind computers, don't make games like MMORPGs that connect other people from around the world. Don't let console games have internet capabilities. Let's all be shut off from the rest of the world and go explore it for ourselves again. Yeah, it's not healthy being addicted, I'm not condoning it. But it seems that everything else points to being crippled by it.
Remember South Park when the internet ran out? Case and point.
