According to the FBI, which investigated, these executives tried to hack into computers to steal the manuscript, and also tried to prevent publication of the book by engaging in extortion. No criminal charges have been filed, but the hacking, extortion, and ensuing cover-up raised questions about HubSpot’s culture and the trustworthiness of its leadership. HubSpot's board fired the CMO, and sanctioned Halligan, the CEO. A vice president resigned before the board could decide whether to terminate him. The board still won't tell me what happened.
That's some HP board level disfunction and paranoia. I think there is bit more wrong then their age bias, as they lack a moral compass.
