    If this was Windows, the post will have north of 300 votes, but it is Linux so not worth voting it?

        Still, my point remains valid.

          Windows has an overwhelming market share in PCs. Exploitable vulnerabilities that let hackers own it are going to be huge news for as long as that remains the case, because it directly impacts the lives and personal data of more people.

          That said, I’m seeing lots of people talk about this particular Linux vulnerability, so I’m not even sure what your gripe is.
