Hello I'm the developer of NoiseTorch (https://github.com/lawl/NoiseTorch/). I faithfully believe that the package "noisetorch" in the ArchLinux User Repository ("AUR") (https://aur.archlinux.org/packages/noisetorch/) violates my license (GPLv3). I have the asked previous maintainer of this package to not apply patches or make it clear that this is a fork that's being conveyed. Several Arch Linux trusted users were also informed of this: https://github.com/lawl/NoiseTorch/issues/2#issuecomment-785262068 Unfortunately this seemed to have little effect, forcing me to officially notify the ArchLinux project of this violation. The GPLv3 in Section 5 clearly states that modified versions must be marked as such
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
The term conveyance is also clearly defined in the GPL:
To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.
Since AUR is distributing packages to automate the process receiving modified versions of the source code, I believe this constitutes conveyance of a modified version, irregardless of where the original source code tarball is fetched from. Please ensure the cessation of violation of the license immediately. Regards lawl Sent with [ProtonMail](https://protonmail.com) Secure Email.
