No, it is misleading. An exploit with no remediation is not remotely comparable to a normal root exploit, which can be fixed with a simple OS reinstall.
Edit: And their follow-up comment, “if somebody has ring 0 access that shouldn’t, you already have problems,” is dangerously misleading. While technically true that you would have a problem in both scenarios, presenting it that way is like telling someone not to worry about losing a leg because their sprained ankle is already a problem.
