Would it be more clear to say 'Operating System," instead of OS.
Like Ubuntu is an ‘Operating System.’
Like “Windows,” is an Operating System.
By ‘tiny,’ Qubes has very individuals using it. Suggesting that ‘safe by being tiny’ those who might want to penetrate, or observe, what we are doing on our computer, That is a power group who has resources to use against Qubes, like Google (wants info on us to sell), or a government, would not bother, because the number of Qubes users small, tiny.
Like what happened to the Apple Operating System for years, they represented such a few users, the people who wanted to exploit did not bother trying to hack the Apple OS (well not as much as Windows.) In addition, Windows Operating Systems were so easy to hack, had a lot of folks who did not update. Now Windows is designed to spy on those using its Windows Operating System.
Plus we have gone through a stage where Malware is designed to hack into Browsers, less about which Operating System.
Qubes can prevent that by presenting a new clean Operating System with each internet exchange. A clean version of the browser with each Qube.
By comparison. A big danger in any OS is “How we use it.” Meaning we give up our security or privacy (depending on your goal) by doing the wrong things at the same time. Or downloading Malware into a Template Qube. Well there are other ways.
While one of the goals of the developers is to make it more difficult for us to easily corrupt ourselves.
I like the example of a college student developing an idea, which he wants to protect his rights to, from having someone else steal it.
I would like to say an ordinary person, a non-computer geek, who is reporting a human rights issue, and protecting himself from revenge by power groups, governments. While there is someone working on making it easy for Qubes to be used by those reporters, Human Rights Activists, without their being detected. Well, it takes some knowledge or experience.
