Skylon was basically knocked out by Falcon 9, and even more so by Starship.
Skylon doesn't even save on propellant cost. It uses more expensive liquid hydrogen in order to save very cheap liquid oxygen.
The only reason to continue to invest in this is if one imagines there's some cruise mission application for the technology, say hypersonic cruise missiles.
