I'm pretty sure most of these counter points are Facebook team accounts.
Reasonable short term counterpoints to opposing Internet.org exist —more access and faster. Facebook is leveraging those counter points into a market strategy that undermines one of the central value propositions of the current open internet.
It's defensible; it's not all bad. But its not ideal; it is distinctively bad in a serious way.
Ideally Facebook would promote access to the open web, rather than undermine it by promoting access to the Facebook version.
