Sorry to interrupt your pitchfork campaign, but is there some set of information that we know this could be based off of, i.e. some sort of legally mandated report for shareholders of private companies? This is not my area of expertise nor am I in the US/familiar with US rules, but this thread has me curious.
Shareholders are usually legally entitled to quarterly or year end financials at a minimum, even for private companies. Though I don't know if any such reports are available yet to investors.
