This paper is mainly for teaching purposes. A DNS system is a great example that shows off the capabilities of ETC.

Even though Ethereum (the real one) has been implementing this for a while now? What is the reasoning behind using classic?

Yes. The reasoning behind using ETC is because I prefer it. See the "Why Classic?" docs here: https://ethereumclassic.github.io/

Haha well I clearly don't align with those viewpoints but awesome work fighting for decentralization. A ENS like system is going to be crucial for the future decentralized world. Maybe you can work on porting the ENS to classic, or is that an active area of development?

I don't know if anyone is working on porting ENS. I focus on educational materials but maybe someone reading this might be interested in porting ENS or creating something similar.

because Ethereum has a history of censorship, so virtually any other service is superior. https://www.reddit.com/r/ethereumfraud/

Well you're fine staying on your fork, there is no problem having different chains. I happen to side on the Ethereum Foundation's side, I have seen everything on that subreddit (I even subscribe) and I recognize the room for argument.
