Allegations of copyright infringement by the MPAA
In 2007, English software developer Patrick Robin alleged that the MPAA illegally used his blogging platform, Forest Blog, which is distributed without cost under a linkware license, whereby users must link back to his site. To remove these links, one must secure a license, but Patrick Robin claimed the MPAA removed them without purchasing a license. The MPAA responded that it was only testing the blogging platform and that the blog was "never advertised to the public in any way."[citation needed]
On November 23, 2007, Matthew Garret notified the MPAA that it was in violation of the GNU General Public License (GPL) for distributing a software toolkit, based on the Xubuntu operating system and designed to help universities detect instances of potentially illegal file-sharing on school networks. Garret alleged that the MPAA violated the GPL by distributing a derived work without making source code available. On December 1, 2007, Garrett notified the Internet service provider for the MPAA that, in accordance with the Digital Millennium Copyright Act, he was requesting them to disable the offending distribution web site. The MPAA subsequently changed its site so the toolkit was no longer offered for distribution.[22]
