It's not wrong. Linux does not have a great security track record, it was built on completely different security principles than the ones we have today. You can find public criticism from Theo de Raadt and grsecurity if you want to find out more.

It's a kernel that has served us well, especially considering its ubiquity, but it will never be a "secure" kernel.

Everything is relative of course but it's a consensus view in OS literature that the Unix family of operating systems doesn't have strong security. There's a huge TCB in which bugs lead to vulnerabilities with high probability, as we see all the time.

This is why eg cloud providers don't rely on the OS to isolate customers from each other.

Since the reneissance of virtualization, many security focused systems have built on that, like Qubes OS, seL4-based virtualized systems, etc.

It sounds like a cool project and I hope it continues development, but there is such a huge graveyard of such projects that have never gone anywhere that I struggle to get excited about them anymore. Replacing Linux is really hard, even for specific uses like cloud.
