I mean, but we pretty much do know? The difference between Linux and Windows / MacOS is Linux is open source and can be checked and audited by anyone. If an exploit exists, it will be visible publicly and just needs to be spotted by those knowledgeable enough. Windows and MacOS are more than likely audited too but by private companies under NDA, so then it’s left up to Microsoft or Apple to decide what exploits are fixed.
Not the original commentor, but the people I’ve discussed this with usually say one of 4 things. These aren’t necessarily my views, just what I’ve heard from others:
Yeah Kiwix is great for this, I just put together what this company is essentially selling for free by myself a few months ago. In fact I would be surprised if this company wasn’t using Kiwix as most of the resources they listed are on it already.
My internal clock is similarly good, but more of an asshole. If I fall back asleep after an alarm accidentally and have somewhere I need to be, my body will wake me up with the absolute bare minimum amount of time I need to get ready if I rush like an absolute mad man.
Ah yes, I think that was when a FOSS maintainer had to step down and handed it off to someone else if I remember right? See this XKCD for relevance. It’s pretty ridiculous how much we (and companies with billion dollar revenues) rely on the free work of others for such important systems. But yes, an important distinction to make is that certain Linux distributions may use code by others that is not open source and malicious without them realizing.
