Bitcoin wouldn't be worth $59k each if it wasn't open source. "Don't trust, verify." is one of the most important fundamental points about Bitcoin. That can't be accomplished if it's not open source. And yes, having it open source enables other developers like us to develop it to a different direction but make no mistake, we respect the original Bitcoin as it is a fine replacement for gold and a good way to store wealth without having it inflated away. It lacks in speed, scalability, privacy, and uses too much electricity. Those points Bitcoin 2 improves.
It's because of this thought that BTC 2 has the requirements to be a good alternative of value and use in relation to BTC. Many projects have the intention of becoming the new BTC and end up failing, naturally the mindset of BTC2 is totally different. Naturally there will be demand and adoption, so prices will go up.
