In June 2014, most interwiki links to TV Tropes were changed to point at All the Tropes as a protest against changes to the contribution copyright policy of TV Tropes in July 2012 and November 2013. An interpretation of another major wiki's policy against linking to copyright infringements supported this change. To do this, Tepples wrote a query that scans a file created with a wiki backup tool and produces a list of pages linking to TV Tropes, sorted by the source page's namespace and the number of distinct target page names. Mainspace was completed in June; other namespaces were completed gradually over the following six months. This also encouraged a more general review of these pages, such as copyediting, updating the text to reflect new information, checking other external links, and the like.
The following SQLite query was run periodically to track the progress of the project.
The count included only the
trope: interwiki prefix, not
[[tvtropes:Like This One]]), because pages discussing policies of TV Tropes still need to point to TV Tropes.

Then TV Tropes sublicenses the contributions to the public under the non-free CC BY-NC-SA license. Under the nonexclusive license model, unlike the assignment model, authors can dual-license their contributions under the free CC BY-SA license.
