Software startup JasperSoft acquired Sourceforge-based project 
<http://jasperreports.sourceforge.net/>JasperReports, which involved 
acquiring the copyrights and hiring the lead developer for the project." I 
guess the point he tries to make is that the new corporate overloads can 
essentially have a free and non-free version of the code, and more or less 
orphan the free version. The problem of course is that if the non-free 
version gets good, others will simply fork.
