Have the people who funded Theranos been calling the critics haters? That seems to be common with some VCs. Like calling HN "Hater News" because of harsh criticism of questionable claims of innovation.
We all understand that the VC narrative is about potentials. Sometimes we don't buy into the potential, may even have legit reasons to believe it is bogus. But if we don't support the narrative we are haters. Seems beneath someone in that position to resort to name-calling.
