If you believe there was no corruption, collusion or conspiracy and that opinions of people around you constitute the consensus reality there is nothing I can tell you to stop you from using the Core version of Bitcoin. Bitcoin is not a popularity contest of opinions. The nodes have spoken and the chain has split. People do not gravitate towards Bitcoin because its popular but because it provides decentralized permissionless solution to money. If you're in no need of such solution it doesn't matter what you do next. But if such solution is what you need you'll end up diverging from the centralisation of the entire bitcoin ecosystem. And once that centralised ecosystem turns on the nodes, the social contract is broken and the network naturally defends itself and that's why we are here and that's why people don't want to go back to Core. Parting ways and rebuilding is the right thing to do.
