Is Fabien actively involved in coding GnuChess 6, or is it just an adaptation by other authors ?
Fabien is not actively involved in GnuChess 6 but he donated the copyright for Fruit 2.1 to the Free Software Foundation. So everything is both legally and morally correct.
GnuChess 6 (which is the official FSF GnuChess) was mainly created by Antonio Ceballos. It uses an embedded Polyglot to connect the Fruit code to the standard GnuChess interface.

To test the Android binary, I ran a one-second-per-move, 32MB hash tournament on a Nexus S, using the Silver Opening Suite, with Gaviota tablebases on the SD card. Below are the results. Although the latest release was mainly for FRC support, it also seems slightly stronger.
