There are already several aftermarket suppliers making parts for them, including a drop-in e3d hot end. Look, I generally prefer open source designs, but the hassle-free workflow with an X1C has been worth it.
Also, they sold a PILE of these things, I suspect aftermarket support will continue even if Bambu stops.
It has definitely come a long way from my first attempt with it. It's really usable now and I suspect it will only get better with a larger user base.
