What evidence? If they choose speaker based on purely technical factor and ended up with all white-male, why must they change the result?

You're right though that we have no real evidence for this, this is just a natural assumption to make given the evidence we do have (the lineup).
As a poster said above me, this could have possibly been mitigated by publishing who they considered and possibly even selected that were non-white/male and couldn't make it. (this would give us some of the evidence you mention).
