I don't doubt this, but I think Facebook has a flawed culture that allows and encourages employees to use this mindset as a rationalization for unethical things like:
- run emotional experiments on news feeds
- silently logging all Android users' calls and texts
- allow proliferation of fake news
- allow buying of propaganda ads from state actors
- zero safeguarding of data to ensure it wasn't sold by app creators/devs.
Data is central to facebook's business model and the ability to collect, analyze, and sell lots of data (a natural result of the 'big data' hype) became an infatuation for facebook employees.
The Boz memo supports my point - except he cleverly hides it as 'grow at all costs' rather than the underlying 'collect/analyze/sell data at all costs'.
