Fuse jest GPL2, więc portując czy modyfikując muszą to udostępnić.
Otwartość kodu nie ma tu nic do rzeczy...
masz rację, nie open source, ale muszą udostępnić zmodyfikowaną wersję.
https://sourceforge.net/p/fuse-emulator/mailman/message/35689482/The Fuse team note today’s announcement from Retro Computers Ltd that the
Vega+ handheld will be using a modified version of Fuse to provide its
Spectrum emulation, and that Retro Computers Ltd intend to fully comply
with their obligations under the GNU GPL to provide the source to the
version of Fuse which will run on the Vega+. Portability has always been
one of Fuse’s goals, so we are pleased that it has been able to be made to
run on another new platform.
For avoidance of doubt:
- The Fuse team were not aware that Fuse was going to be used in the
Vega+ until the end of 2016. One of the fundamental tenets of open source
software is that there is no requirement to communicate use of the
software, so this does not represent any breach of the GNU GPL by Retro
Computers Ltd.
- No members of the team were involved in the porting of Fuse to the
Vega+.
- No members of the team have received any compensation, monetary or
otherwise, for the use of Fuse in the Vega+.
Given the ongoing disputes around the Vega+, the Fuse team do not intend to
make any further statements on this matter unless there is a material
change in circumstances.
