From the new terms of service

Some or all of the Service may be supported by advertising revenue. To help us deliver interesting paid or sponsored content or promotions, you agree that a business or other entity may pay us to display your username, likeness, photos (along with any associated metadata), and/or actions you take, in connection with paid or sponsored content or promotions, without any compensation to you. If you are under the age of eighteen (18), or under any other applicable age of majority, you represent that at least one of your parents or legal guardians has also agreed to this provision (and the use of your name, likeness, username, and/or photos (along with any associated metadata)) on your behalf. 

What this means is that Instagram can now effectively sell the use of your username, profile picture, photos you’ve taken and records of what you’ve liked or commented on to another company — like an advertiser — and they don’t have to pay you in order to do so. And you can’t stop them.

Facebook’s terms in this regard are similar, but Facebook does explicitly grant you the ability to adjust how your name and profile photo are used for ads and commercial content:  READMOREHRE

Julian Assange’s new book takes on some of the issues:

Cypherpunks: Freedom and the Future of the internet is the title of the book and its introduction was written in the Ecuadorian embassy in London, where Assange has been seeking to avoid extradition to Sweden to face sexual assault claims during five months.

The 192-page book was published on 26 November, in digital and print form, and Assange calls it a “watchman’s shout in the night” warning that the net can either free us or enslave us, but stated that it’s not a manifesto.

In October, the Australian internet activist, announced his intentions to publish a book, based on the transcript of an interview conducted earlier in the year with three fellow “cutting-edge thinkers” on the web, and broadcasted on the Russian state-controlled TV channel RT.
