Critics say, Facebook, Internet.org "violate freedom of expression and privacy"

Internet.org, Facebook securities services who want to bring free internet to people in emerging markets, apparently, can not catch a break.

More than 60 civilians and digital liberties groups from 28 countries signed an open letter to Mark Zuckerberg said Monday that Internet.org in its current state violates net neutrality, thus "threatening freedom of speech, equality, security, privacy and innovation."

Internet.org, which Zuckerberg launched in 2013, collaborating with local companies TELECOMM and developers to offer free, basic Internet experience with access to things like Facebook, Wikipedia and BBC News. Facebook revealed earlier this year that Internet.org helped more than 7 million people in all six countries still - Colombia, India, Zambia, Tanzania, Kenya and Ghana - and want to be in 100 countries by the end of this year.

Zuckerberg sees this "Internet for all" approach type, but critics see things differently. Last month, for example, a group of Internet companies pulled their support from Internet.org in India after the decline in national net neutrality.

Groups defense this week adopted a similar tactic, saying, Internet.org actually be "zero rate" model where suppliers provide a variety of services or programs that are free to use without a data plan or do not factor in terms of data use. Worse yet, they support Internet.org can create a "two-tier Internet" scenario in which new Internet users "stuck on a separate and unequal way for Internet connections that will serve to expand - not narrow - the digital divide."

Facebook, in turn, tried to address criticism recently rolling out the platform Internet.org earlier this month, allowing outside developers to create free service. Thus Internet.org trying to cut back on the argument that it is a priority partner content above the rest - one has no network neutrality.

"We and our critics share a common vision to help more people get access to the widest possible range of expertise and services on the Internet," said one representative Internet.org Mashable in a statement.

"We are confident that more and more people access the Internet, they will see the benefits and want to spend more services. We believe it so much that we are working with operators to offer basic services people without charge, convinced that new users want to quickly move beyond basic services and pay more diverse, valuable services.
