In such a scenario, wouldn't an alternative/forked browser emerge with support for an HTTP/anonymous web?

There is also censorship risk in named-data and content-centric networking, which offer multicast and caching benefits, but rely on uniquely identified content.

certainly there will always be alternative browsers, but since they would be used by a small minority the censors would effectively have the ability to determine which publishers are "cleared" to reach out to the most broad demographics. That alone would be enough if your censorship goal was to be able to sway public sentiment.
