This is about Spectre, not about buggy hardware implementations.

Spectre is a fundamental flaw in speculative execution that means it can leak information, so it's a security vulnerability. Apparently Intel has been imposing draconian requirements on software to work around the issue rather than fixing it in hardware, which is obviously what they should do, but is not at all trivial.
