I don't believe the SEC was wrong to suspend any of those stocks, because as you outlined there were several reasons not to touch this (and each of the other tickers).
Without looking into each of those stocks, at a minimum there would be questions about the accuracy and adequacy of the information.
I just believe the suspensions should have happened much, much sooner, which would have limited harm to investors. Timing (hitting the nail much faster) is where I believe the SEC failed, not the actual act of suspension (hitting the nail).
