This type of conspiratorial nonsense would be thoroughly trashed here if a startup was "the big guy" in this story. Instead the nonsense flies because the FDA is the baddie here. People are just telling themselves things and don't care to find out why they took action against 23andMe in specific, or their regulatory purpose in general, mixed with generic gov't mistrust. Bring in guesses about financial benefits to larger companies and you've got a stew going.

I've had a professional relationship with the FDA for a few years. Sometimes I like what they do, sometimes I don't. I'm not going to show my hand on how I feel about them (or their 23andMe action) any more than that. Ever since the FDA sent the warning letter, the reaction online reminds me of the Pavlovian whining I hear from folks in the industry every time the FDA issues new guidance that effectively says "don't cut corners X Y and Z" regardless of the merit in the FDA decision. You'll have to forgive me if I'm unsympathetic, I read way too much of what comes out of the FDA to stomach the broad knee-jerk against everything they do, or middle management suits just looking for something to bitch about.

edit: Rolled my already not-saying-anything about the FDA back even further, I'm talking about the response: http://i.imgur.com/tAfqLKY.png
