The main point I took away from this article is that the younger people today, Millenials if you will, are not used to an open internet, so they see the internet as a closed gate community, a divisive force. A completely different view of the Internet than the previous generation had. And as the younger people are the ones with the most energy to fight against what they perceive as injustices, they tend to actually dominate policy making even if indirectly, and what they see as the enemy is things like encryption and even privacy, which the previous generation saw as essential for a free Internet.
I agree completely with that, but I am not optimistic as the author is that GenXers will at some point get their act together and make the internet more open again. I believe what will happen is that the Internet will continue being this divisive force until legislation (pushed by younger people who don't know better) is introduced to curtail freedom of expression and remove all privacy in the name of justice. That will be a very different Internet and not in a good way.
