<i>we needn&#x27;t just shrug and say, &quot;They made a bad investment, so what?&quot;</i><p>Well I haven&#x27;t made a statement on that either way - but I wouldn&#x27;t advocate for that.<p>It is however up to their own judgement how much to do in any case. They represent shareholders, so they do have fiduciary duty there to be sure (though I am unsure if that is true for the high profile members of the Theranos board as it seemed to be largely advisory).<p>The fact that Holmes has 50+% of the company makes the point in this case pretty much moot. Aside from leaving the board en masse and abandoning whatever shares they have, they really are pretty powerless.
