Another good comment from link above:
I used to be a "internet-optimist" also believing universal internet access is a good thing, and maybe it is in the longer run.
But right now, the web is badly broken. Most of these new users Mr. Zuckerberg wants to get online have no clue about the dangers, both cultural and technical. There are efforts by various foundations (eg: Mozilla [mozilla.org]) to educate new users, but they are hilariously mismatched to the big internet giants who want to siphon of people's privacy for $$$. On top of that you have the Snowden revelations
I work with many rural communities in India, and often the question of providing internet access comes up. Unlike before, where I would say an unqualified yes, I do not support providing internet unless there is a deep discussion held with the stakeholders. What is (pleasantly) surprising though is that usually the elders in a Village are quite concerned and want to discuss these issues.
Does Mr. Zuckerberg have it in him to have those discussions?
