Pretty much every "meditation was bad for me" story seems to play out like this. The author basically abused meditation in the way that someone might abuse drugs.

Some people clearly are susceptible to being caught up in this kind of behavior. So I think the point in TFA: "meditation can have risks for some people" is valid. But that "some people" seems to be a fairly specific personality type, and most people could probably benefit from some mind-calming body-centering breathing exercises every day.
