But did they "get the fix out"?

They released some binaries, built for their own docker image based on their own Linux distro. Other people couldn't use Chainguard's "fix" to patch their own systems. The only people who seem to have benefited from the stunt are the hackers who used AI to reverse-engineer the binaries and write exploits.

That was a giant fuck-you to the rest of the PHP ecosystem, nothing more.
