I am not a lawyer of course. I do work with some really good ones. Like
each of you, I do listen, learn, and try to pick up what I can to
Stating it plainly, there are noteworthy firms that have sufficient
concerns about LGPL that they will strive to avoid it. These are
respected firms such as Nokia
and many others.
It's about friction. The IBM link above is a good one to review and
consider in this regard.
The Eclipse Foundation, and by extension the LocationTech
<http://wiki.eclipse.org/LocationTech> working group are designed
carefully to minimize such friction while simultaneously balancing
benefits to projects. These policies seem to be reasonably effective
based on the success of Eclipse software.
The Eclipse Public License is a central part of reducing friction while
maintaining balance for the project's well being and interests. It is a
weak copyleft license. In short:
1. If you modify EPL code and redistribute, you are obligated to share
2. If you build on top of EPL software, your own software can be
licensed under your own license of choice (assuming no license
3. You can also re-license the finished product under a commercial
license of your choice
LocationTech also allows other business friendly licenses like MIT, BSD,
In our license choices, IP policy, and other processes we're trying to
ensure things don't needlessly hinder projects from being adopted by
anyone and especially those people who might help you make a living from it.
