Every system has "architectural" flaws, 0days and CVEs, that's just a normal day in infosec.
What matters is in practice and in the wild. The fact most internet infrastructure uses Linux is not some collective delusion based on a "common security misconception".
It's years of practical experience at play. If they were really better off using some other OS, the free market would guide it towards that.
That's a very good point. Even if so many kernel vulnerabilities are known but just not fixed like the article claims. And even when there supposedly are teams who can penetrate into any system on the globe if given enough time, that shouldn't be on the threat model of 99.9% of the people. I think the most prudent action for the security oriented pleb is to just start using Qubes and some airgapped cold storage method.
