Technical Snafu Destroys Screenplay Site, Loses Scripts Forever (linkedin.com)

The tone and content seems overly negative towards a service that the author admits he didn't fully use.

  "Hollywood and Silicon Valley have had their share of
  catastrophe and tragedy due to corner-cutting, but 
  they have something that startups and indies do not:
  piles of money to properly create redundancies, properly
  hire and manage employees, and purchase insurance to
  protect the company from errors and omissions."

That's a weird conclusion. Other quotes and screenshots that the author shared reflect favorably on the company, not negatively. Waiting a few days to share findings from a detailed post-mortem shows maturity and transparency.

Why wouldn't writers keep a local copy of scripts?
