ETH newcomer who just read up on the ETH/ETC fork from 2016

So I just read “Out of the Ether” by Matthew Leising and it describes the DOW heist and how that lead to the hard fork creating ETC as well as ETH, and my question is why would anyone want ETC 5 years later? Clearly ETH is the superior product but what is driving the residual value? Are there philosophical arguments that prop this up? Is it purely based on value for values sake from the people who ended up with ETC at the fork? Have people developed on top of ETC as well as ETH? Or is it a complete scam? I guess I just don’t get why years later it hasn’t dropped to 0.
