People in this thread say variations of your comment, that it's obvious, that everyone knows it.

But then at the same time people still make excuses for companies like Facebook. They urge others not to assume any bad (or purely profit oriented) intent, to believe that the people working at Facebook are honest about what their PR campaigns and Zuckerberg claim and the list goes on...

Also it is absolutely common that people really want to give companies the benefit of the doubt when it comes to morals vs. profit.

So it's clearly not that obvious to most, it's just that people agree if you phrase it the way this headline does.

Also still everyone does the dance of company marketing and "mission statements". Quotes like "we here at <generic megacorp> want to make the world a better place" are still often taken at face value or repeated outside the work environment.

It's not clear, or if it is, most still play along.
