There are a large number of Free-Libre / Open Source Software (FLOSS) licenses, but only a few are widely used.

The following “license slide” figure makes it easy to see when common licenses can be combined:

Why Open Source Software / Free Software (OSS/FS, FOSS, or FLOSS)? Look at the Numbers!
This paper provides quantitative data that, in many cases, open source software / free software is equal to or superior to their proprietary competition.

Time for Net Giants to Pay Fairly for the Open Source on Which They Depend | Linux Journal

Recently, there have been two such flarings of strong feelings, both of which raise important issues.
