I'm sorry, but this is such an extreme example. You should not overdo anything, be it meditation, gaming, playing, reading, any sport, even drugs. Drugs also give you a state of mind that, when taken to the extreme, can harm your social life and well-being. That is not a problem specifically of meditation.
You can safely do anything up to the point that it benefits you. The moment your well-being suffers, or you neglect important parts of life, like friendship, you should stop.
That's what I did. I mean, my story is quite unique in that I never knew what meditation was (or religion, to be honest) and it just fell into my lap.
I think, looking back I can safely say that it did help me address a lot of emotional trauma. I didn't exactly have a gentle upbringing and I somehow entangled myself into all those memories.
Meditation helped me to clear the air, but as you say - it blindly became a somewhat of an addiction. So I stopped and started focusing on other things. And I still have a long way to go.
From the article, it sounds like the author was spending more than just 40 minutes a day on their spiritual pursuits. They also didn't describe their actual practice.
This thread seems to be full of people trying to debunk meditation as some kind of dangerous dark art.
