My web pages are personal and don't have ads, I don't have a "donate"
button and I don't want money, I already have all the money that I need.
This is a personal project just for fun, so the non-commercial
restriction should not be problem for me. Just asking.

I want to take some parts of that source code for another program which
already contains GPLv3 source, derived from other free software
projects. Since I can't downgrade the GPLv3 to v2, the only solution is
to upgrade v2 to v3 in order to combine all parts.

The program that has the additional restriction is linuxsampler
( http://linuxsampler.org/ ). I already asked to the authors, replied:

  "no matter if GPL2 or GPL3, the commercial exception still
  applies to LinuxSampler and derivative works" [...]
