Vitalik cannot create a personal initiative to change the ethereum protocol. Ethereum itself has a
repository of EIP lists from the community and the implementation approval involves the entire core team. Since its launch ethereum has had 2 forked coins as forms of rejection of the new protocol, ETC and ETHW. Assuming ethereum will have a lot of ecosystem chaos after changing leadership and no longer using the EIP system as consideration of improvements, I think there will be many other forkedcoins in the future.
Regarding price, I still believe that the law of supply and demand applies. In fact, what we expected went the other way, people don't care about de/centralized.
ETC is not a fork, but rather the continuation of the original Ethereum Blockchain. The real fork is ETH with "The DAO" rollback voted only by a few members of the community (but pushed by Vitalik himself). You can see how he still has a strong influence over the project. ETH might survive without Vitalik, but things won't be the same. He's the "mastermind" after all. It's no secret that the ETH blockchain became more centralized after the transition to PoS. If developers don't address this soon, ETH might hit "rock bottom" in the future. I really hope it makes a comeback as a decentralized alternative to Bitcoin. With decentralization, ETH will survive in the long run. Who knows how far will the cryptocurrency go? Just my thoughts
