Bizarre article, trying to argue open source is insecure because somebody spotted a deliberately inserted vulnerability - you get that you just showed why it's secure, because there is no shortage of eyes to spot problems including attempted skull-duggery, right?
The fact the vulnerability was found just highlights the benefit of open source, not the other way round. The MS Engineer just confirmed (Again, like many others have done), why all software should be open source.
Look at the power requirements of two operating systems, proprietary windows, and it's nearest competitor, arguably Ubuntu, which is open source.
Ubuntu runs at about maybe 10% of the energy requirements of MS Windows doing comparable tasks.
Why does Windows need so much more power?
Because the other 90 percent of energy on the Windows system is being used by what is effectively software Enshittification, most of it is doing things that neither the user nor any single Engineer in Microsoft intended, it's all about grabbing the user data to report back to all the profiteers who all work together, and yet all in competition with one another, to fight over the internal resources of the machine, to get most profit out of their various activities, mostly unknown, proprietary, hidden.
I'll let you work out whether that makes your machine more or less intelligent.
The same thing actually applies to humanity, the bullshit business and Enshittification exists also in our human affairs.
It seems crazy to me we don't get this, it's just evidence that the general burden on most people's thinking, by Enshittification, is so bad that it is literally dragging down our ability to see it all for what it is - useless waste of energy.
