When it boils down to licensing and availability of application/component source code
....then it becomes a bit more complex than the (affectionately put) average shmoe might be expected to comprehend.
Of course, that may be only one visible side of the matter - namely, the licensing of the components, themselves - but, I digress.
I think it must be a fine situation, if the market - collectively - may finally be maturing past the point where the situation would have been portrayed as if it was no more than a matter of some sort of abstract yet personal competition between "closed source" and "open source" agency and individuals. Certainly, the use of open source components does not change the fundamental laws of business and competition - as compared to those same laws on which business using only closed-source components will also have to operate, along with the natural limitations on their applications' available service lifetimes, and so-on. As far as who's competing with whom, though, as I see it, it boils down to no more and no less than: Business competing with business - as far any essentially useful, more-than-ephemeral competition in the market would ever occur.
If more companies are finally learning how to make such software as would be made available on open source licensing models, to make that software and the licensing terms on it work, in their competitive endeavors, and there's no more of such as SCO's polytricks, then I think, that's wonderful - and what a year it must have been, after all.
To a better 2011, and so on.
