For the records, and unless I'm missing something, this seems to be at
the same level of "scientificity" of the yearly report by Black Duck: we
don't know what's in the database of "over 3M open source components and
70M source files", we don't know what they count to produce the pie
charts (files? "components"? popularity? etc.), nor we have access to
the code used to due the counting.
I'd be glad to be proven wrong and pointed to all the details (data,
source code, etc.) that allow to independently verify the results of
that (and/or similar) studies.
