> But Facebook's founder Mark Zuckerberg said it was "not sustainable to offer the whole internet for free".
Quite plainly, that's false. 1Mb of an internet.org site costs operators exactly the same to carry as 1Mb of some other website.
Operators obviously have some average Mbs/user/month figure that they're willing to bundle as internet.org, expecting to recover this from the people who upgrade to a full internet plan. Whatever this number is, users can also be limited to this with a data cap, allowing them to There would then be no net neutrality concerns at all.
Facebook could continue to have the internet.org app, their proxy server, and they could be displayed as a default to the people on this plan. Those users would prefer them (they would really need to conserve data). It could even warn people about data consumption when they open the browser, as long as there is an option to click through. None of those things violate net neutrality, and they will keep 99% of users within the internet.org app.
Facebook has never said why they cannot do this, other than offering hand-wavy "poor people don't understand data caps because they don't know what megabytes are". This is false. Anyone who has a prepaid phone connection in, say, India understands how to navigate the bewildering complexity of phone plans (pay Rs. 30 to decrease the cost of calls by 50% between 10pm and 6am for 30 days). As long as there is some way for users to check how many MBs they have left, they will be fine.
I suspect that the real reason facebook opposes this is that they want to use their position as gatekeeper to shut out competition. If these "starter internet plans" operated as I described, Google will soon have its own "Google+ zero" built into Android.
Thanks to Android, Google enjoys unassailable market power as a gatekeeper on the device. The only way facebook can close that gap is by becoming the gatekeeper at the network level, which requires that net neutrality be subverted.
