Requiring registration of GPL software
Sorry if this is not quite in-topic for debian-legal. I run into E4, a
collection of Matlab functions, distributed under the GPL.
However, the software can be only downloaded as a zip file protected by a
password, which you can get only by contacting the authors: this effectively
equals to requiring registration of the software.
Apparently, this is in contrast with the GPL (see ). I'd just like to be
sure before (politely) informing the authors of this.
A quote from the download page follows:
E4 Toolbox is redistributable software. You may redistribute it
and/or modify it under the terms of the GNU General Public License
(GPL) as published by the Free Software Foundation.
For the moment E4 Toolbox is distributed in a encrypted zip file.
CONTACT us to get the password.
