Are you saying that closed source is more profitable???
No, I'm saying there is no correlation between open or closed source and stock value.
It's about the product - not some abstract philosophical/idealistic criteria. Or, as 'Zilla put it, most consumers give a hoot about whether or not their gadget is open or closed source.
I will say this, though: I cannot think of a single Fortune500 tech company that relies **solely** on an open source business model.
