I'd say he's just changed his opinion on it and the internet itself has evolved. I know my enthusiasm for the internet and technology has rapidly faded in the recent 2-3 years. Mostly that's just due to fatigue. We can do amazing things on the internet but spending 90% of your waking day on it and doing the same few things instead of taking advantage of everything it has to offer can become unhealthy. You don't necessarily have to go 'off the grid' to fix the problem but going cold turkey could be easier. Take for example my recent experience with Twitter. I decided I was just wasting my time on it (and the actual value I get from it I could just get logged out through search) so I deactivated my account. They give you a 30 day period to log in and reactivate it. I've done this three times now. Very smart move by Twitter but it just goes to show how addictive a lot of this stuff can be.
