In particular, the Apache License 2.0 is the most appealing license for "commercial-friendly" open source, whereas the GPL with its "developer-friendly" license correlates highly with FSF-hosted, Gnome/KDE/... or independent projects. The Java/C(++)? divide also seems to correlate with "commercial-friendly" (Hadoop, Lucene) versus "developer-friendly" (Blender, Linux) software.
