So yeah, this very much has a "So please don't buy an AMD processor this year!" feel to it.
Heh, funny story, we're on the plane and the Tandem instructor asks my niece, "Who did you put down as your emergency contact if something happens on this jump?" and she says "My mom!" and points at my sister. And my sister says, "I put HIM down!" and point at me. And I say, "Well I would rather die in a fire plane crash than explain to Gamma how I got her daughter and grand daughter killed taking them skydiving!" Aaahh, yeah... good times... Everyone lived, by the way.
I kid, I kid. In actuality, the problem is that anyone reading the source would quickly realize that just because someone is paid to develop software doesn't mean they crap unicorns and fairies. You see, normal people like to assume that the people who write their software are somewhat competent. So there's a tendency to, for example, assume your web browser is fairly secure. Or that the company writing it actually gives a shit about security. Having the code available to actually read would quickly dispel those assumptions, people would lose faith in technology and the entire software ecosystem would collapse.
Now... aah, I see you looking at open source over there. Stop looking at open source. Open source isn't going to help you here! Because it also turns that that even though the open source guys say their code is more secure because it has more eyes on it, there are no eyes on it. There are millions of lines of open source code out there. Do you know how many have been audited for security? I'm thinking of a number that rhymes with schmero. No one's paying for that, so no one's doing that. And yes, it's probably slighty more than zero audited lines, but if you divide the number of lines that no one's ever looked at by the ones that someone has, it's close enough to be a rounding error.
Er... so yeah, I guess it's fine if they open source windows.
It's a naive, domestic operating system without any breeding, but I think you'll be amused by its presumption.
