It was a fork but it is an altcoin (shit coin) while bitcoin remain the bitcoin.
Keep in mind that bcash is not a shitcoin because it was a hard fork, neither was it because of Roger Ver, Jihan Wu, etc. Instead Bcash is a shitcoin because it created and change and enforced it without reaching majority support. In Bitcoin when we want to change something (soft or hard fork) we first have to reach a threshold of supporters (almost always +90%) before we can move ahead with that change/fork. If we do anything else (like forking with 10% support) we would be creating an altcoin which would be viewed as a shitcoin.
It was because of Roger Ver and Jihan Wu. They ignored the lack of support for block size increase and still did the fork but that was not the only thing that made Bitcoin Cash trash. They started saying that Bitcoin Cash was the original Bitcoin and not Bitcoin Core. They spread many lies and prioritized Bitcoin Cash on bitcoin.com and r/btc. That's why people started to hate Bitcoin Cash too.
I read the discussion and I agree with your points, but having small sized blocks is neither in favor of bitcoin's long term survival.
That's right, small block size will kill Bitcoin. No business wants to pay premium to send and receive bitcoin transactions, no individual wants to pay premium to make a bitcoin transaction.
There are good arguments for every point people make about block size; let's break some of them down.
Argument 1: "Increasing block size would lead to centralizing Bitcoin in terms of nodes."
In theory, this holds. The larger the blockchain, the more expensive it is to store the data.
Counter-Argument: This is B.S. Storage drives are pretty cheap. If someone can afford $50 a year for a node, they could afford $60. Storage is only getting cheaper as we move forward.
Large blockchain is not expensive today. Guys, if equipment price was the problem, then gaming wouldn't improve and would stay on the level where GT series of Nvidia GPUs would be enough to play today. We wouldn't also see the same iPhone sold more expensively every year. I bought a PC for $500 in 2014. I bought a new PC for $500 recently. There is a huge difference between capabilities and space that my new PC has compared to old one. By giving this example, I want to say that everyone upgrades there PC at least once in a decade and hardware is not an issue today to blame it for low block size.
