I changed the license of the software and hardware in the project. Code and hardware remain open source but cannot be used commercially unless you have a license. You are also not allowed to make clones.
I am willing to split of parts of the code base under more permissive licenses if this leads to collaboration.

Motivation

Licensing the whole project as GPLv3 limits my ability to optimize my legal strategy with relation to other rational agents. I foresee competitive pressure from Asia, given the weak European industrial base and high labor prices.
Furthermore, I foresee increased competitive pressure and interest from the Netherlands. This has been increasing its investment in the sector of laser direct imaging.  The Netherlands is strongly against open source.
If you now make changes, I have several options;  acquire a license from you, split of part of the work under a more permissive license which allows us to collaborate commercially or write my own code which achieves the same in another way.
