Its probably nothing in comparison to video games and we dont talk much about that.
The second thing is, that people do talk about the addictiveness and bad effects of games all the time, and have been doing so since games existed.
I know no one who would flunk the school cause he can't glue out of Facebook. I know multiple people who had huge problems in school due to being unable to stop playing or woke up multiple times during night to care about kingdom.
People do get influenced by games and it can lead to problems you have mentioned. However, I do not think that gaming can transform the society as a whole. Social networks have already done it, both in bad and good ways.
