You have made assumptions about what I meant with my original comment. Your assumptions are incorrect. Why not just ask me: "What do you mean by that?"
Here's what I meant. I believe there were naysayers in the 1980's and early 1990's (and maybe they are still around today) who argued open source would never work. I believe history has proved them wrong.
As you pointed out, open source, like proprietary, can produce good results or bad results. It can produce "high quality"[1] results. It can even produce "higher quality" results.
I believe the reasons why open source is as good a choice as proprietary are very simple and quite obvious:
If the user of the software can read the code, then
1. it is easier to evaluate the author's skill and programming sensibilities and
2. it is easier to fix errors and make improvements (without having to pester a proprietary software vendor).
You were also hoping that I would make an argument that the results obtained are somehow related to whether a project is open or closed. As I said, I won't make that argument. And as such I won't look for evidence to support it. That's because I do not believe it.
You have set yourself up for disappointment. I played no part in it.
If you want to know what I believe in terms of how "high quality" or "higher quality" software is achieved, just ask me and I will tell you[2].
But please do not make assumptions about what I think.
All the best.
1. Quality is a subjective determination.
2. I should warn you it is nothing revolutionary. I will only state the obvious.
No. I explained what I meant and you still don't seem to get it. Read what I said about the naysayers again.
You asked for the historical evidence I mentioned and I gave you the example of the TCP/IP stack we're all using.
I shouldn't have to say it but "open source" does not produce software, developers produce software. They might be working on a closed project or they might be working on an open one. The open/closed status of the project does not determine the quality of the software. The developers do.
You appear to be making the same mistake as the naysayers did when they said open source would never work. They believed the closed/open status of a project was somehow tied to quality. They were wrong. (Developers working on) open source projects can produce high quality software just as well as (developers working on) proprietary ones can. You cited the example of KDE's webkit to indicate you agreed.
If this is still somehow confusing to you, then I'm afraid I cannot help you.
Earlier you said: "What's different now is that there is historical evidence that open source projects can produce higher quality software than proprietary ones."
Now you say: "The open/closed status of the project does not determine the quality of the software. The developers do."
