For me it's philosophically reminiscent of the Berlin Wall or the Chinese Great Firewall. Personally, my knee-jerk reaction is that it threatens certain freedoms, but I am also a liberal raised with a Western education.
People's ideas about how their technology should serve them will change over time. I don't want to have to overthrow the old internet before we can try something new, I want it to grow with us--the parts that aren't serving us die off, the parts that address new challenges flourish. If its all one thing, subject to one set of rules, that doesn't happen.
Lucky you.
We need more Western education, not less, which is why fragmentation is a bad thing. My country of birth - in Africa - is aligned with the formerly communist nations; if they had to opt-in to a fragment, it wouldn't have been to the Western one. I might have never been able to emigrate.
Fragmentation seems like a leap backwards in time and a slap in the face of the promise inherent in the free flow of information.
