Consider this: Facebook brought on Joel Kaplan in May 2011.
According to wikipedia:
In May 2011 Facebook hired Kaplan as its vice president of U.S. Public Policy, as part of a Facebook's effort to "strengthen" the company's ties to Republican lawmakers on Capitol Hill.[8] In October 2014 Kaplan succeeded Marne Levine as Facebook's vice president of global public policy.[9]

The first big FTC ding against FB was in Nov 2011. That's some good timing!
Further, before working for Facebook, the wonderful Joel Kaplan oversaw public affairs for Energy Future Holdings. Ok, so what? Well, from the wikipedia for Energy Future Holdings:
Energy Future Holdings owns four of the nation’s highest emitting coal-fired power plants, which together account for approximately one quarter of all industrial/utility air pollution reported to Texas regulators.
And:
The Martin Lake, Big Brown, and Monticello plants rank first, third, and fourth, respectively, in airborne mercury pollution in the United States according to company reports submitted to the EPA.[10][13] Such high levels of mercury pollution have drawn criticism for their harmful effects on child development.[13]
And:
NOx emissions from EFH’s coal plants help contribute to harmful levels of ozone in the air in Dallas and other parts of east Texas, and ozone pollution can trigger asthma attacks and respiratory problems.[13]
So you have this guy that clearly gives zero fucks about "making the world a better place" or whatever Mark says his vision is.
To me, that really says it all.
