It was certainly dramatic at parts but I didn't think the drama was over-the-top. If they're referring to the FEZ guy--he's appears to be a quirky guy that was in a stressful situation (e.g. legal battle). One of the Super Meat Boy guys seemed to be relatively stable, despite his partner also buckling a bit under the stress. I can't comment as to whether or not the situations were exagerated (I've never worked on an Indie Game) but it never struck me as being implausible. I have no doubt that these types of things can be emotionally overwhelming for a lot of people (especially those that may already have issues). I know people that have buckled under far less.
On a side note, for those of us that are in the Linux Steam Beta--none of the games appear to be working when adding them via Steam keys. You'll likely have to install them manually, unless something has changed since reading this.
