Facebook is distancing itself from a whistleblower who has made damaging allegations about the company's practices by claiming she never attended decision-making meetings.
Frances Haugen used to work for the platform and says it puts profits above safety.
She's accused the company of being 'accountable to no-one' and of knowing how to make it safer, but choosing not to.
Larry Lessig is an adviser to the former Facebook employee.
"What Facebook has done time and again is choose between making their platform safer or making their platform more profitable.
"Every single time they chose profit over safety.
"They're kind of a digital tobacco company for the modern age."
