The majority went with Vitalik because they "idolized" him. Even if his actions were meant to compromise the immutable nature of blockchain tech. Well, they took a wrong decision because now Ethereum is a centralized "shitcoin". Fortunately, Ethereum Classic retains the original vision of Ethereum without compromising decentralization and immutability. Even though ETC is not very popular these days, the Blockchain is still very much alive (healthy). Developers made ETC a scarce cryptocurrency by implementing a hard cap in supply of 210m units. It's as close to Bitcoin as it gets.
So if you're one of the "OGs" who love crypto's original fundamentals/principles (like me), you'd choose ETC over ETH any day. Hopefully, ETC lives alongside BTC for a long time.
I guess we have some ideologic differences. I wouldn't sacrifice everyone's money in the altar of what ever "decentralized" means, because i don't see even see true decentralization in anywhere. It's more like a direction but no one is going directly to the center of it, because very idea of it is near impossibility.
Also wouldn't call ETC "healthy", in any other metrics then it's still been mined. Just like every altcoin out there, they have some fringe communities that believe in them. You could even argue that the lead in ETC didn't see the hack coming either, even though hacker warned about the exploit beforehand. They didn't want to cancel the exploit, because having pride for the idea of a faulty code.
They didn't to take responsibility for holders to the extent that they stand that everyone should follow the code, even if the code was exploitable. That really concerns me about their future and how they act on towards of the critique in the future.
Decentralization isn't something that's guaranteed by the code. It's guaranteed by people following the code that benefits them. If majority of bitcoin miners went with rollback because of code they want to fix, and money they wanted back. That wouldn't make bitcoin more or less decentralized, it would just follow the need of the majority; Which is funny enough the very idea of the of any blockchain.
