They are vulnerable to them, but not necessarily affected by them. Consider a computer not networked to the internet and only running trusted workloads (e.g. scientific HPC, etc.). This is why acknowledging that everyone has a different threat model is important. I hope this helps to clarify. Sincerely, -- Katherine
