I helped several friends and acquaintances get their accounts back when I worked for Meta. Befriending an employee is still the best way to get traction. [I no longer work there and do not speak for the company.] Not a single one of those friends or acquaintances used two-factor authentication or other safety features, nor did they follow basic best-practices for keeping any online account secure.

At this point, I think Meta should one if two paths: get broken up into many little pieces or be deemed a utility. And if they go for option 2, then you need to support your users, ROI be damned
