Why didn't Haven work?

After three years, Haven is disbanding.

I have distinct memories of the employer health initiative’s launch. It seemed so promising that three industry giants - Amazon, Berkshire Hathaway and J.P. Morgan - were coming together with a mission to fix health care. Remember how Warren Buffett described the ballooning costs as the “hungry tapeworm” on the economy? It seemed like someone was finally going to do something to fix the most gaping problems.

Of course, there were skeptics from the start who pointed out that these employer health joint ventures almost never work.
