Hi Guillame,

Interesting indeed, I agree that Linux and
ChibiOS/Nut-OS/others-similar have different licensing issues.

This is something that troubled me a lot when I decided to turn
ChibiOS into an open source project. It is true that a BSD or similar
license would offer the greatest freedom for users but that would mean
for me to automatically surrender any right on the code. I also felt
that releasing something, basically for free, under a BSD license
could devalue it somehow. It is free, it can't be really good, right?

It is also true that a GPL license makes a "linkable" OS unusable for
commercial applications so I decided to offer it under GPL3 with a
linking exception AND alternatively under a GPL-free proprietary

Hobbyists, students and small commercial users don't have problems
with GPL+exception, big corporate users usually don't want to be bound
even by a watered down GPL. IMO GPL is actually an advantage if you
want a project to remain truly open AND also try to be profitable.

So far this GPL+exception solution proved to work pretty well, the
project is growing nicely.
