Comme indiqué par Wikipédia, une discussion autour de la discontinuité de la licence GPL se pose, car Torpark était sous licence GNU GPL, et XBBROWER est fermé:
xB Browser is released under the Torrify Ethical Software License Agreement, or TESLA for short. This license is derived from the Hacktivismo Enhanced-Source Software License Agreement, which is employed by Hacktivismo. This type of license states that private use is unlimited, like GPL. Unlike GPL, it also prohibits modification of xB Browser for commercial profit.
On January 30, 2009, John T. Haller posted to the PortableApps.com website that XeroBank is violating the GPL. The original TorPark browser was based on the code to Portable Firefox, released under the GPL, and he assisted with the creation of the original TorPark browser launcher, also licensed under the GPL. The change to the TESLA license was done without his permission and the current XeroBank browser that grew out of his original GPL code still contains some elements of his code. Haller announced his intention of reposting the source under the GPL on a new SourceForge project and involving the Free Software Foundation and the GPL Violations project if further clarifications are needed.
