As the story progresses, Dollars basically starts getting hijacked, and as its members become involved in the gang war, it practically slowly becomes a crime gang in of itself. Zuckerberg hates this and goes around places banhammering and punching people because he wanted to create myspace but created /pol/ instead.
This does not really work out, so he does his best to ruin the gang and crash the site at the end, hoping that the memory of what Dollars was for like the first year or however long would inspire people.
I guess you could talk about the 'ideal is immaterial and only the dead can be saints' and stuff, but it looks more like Narita himself trying to reconcile the themes he set out for himself being directly opposed and making about as much sense as the protagonist.
