PD have a license (a "Standard Improved BSD License"), but GPL is more secure, not ? What are the reasons for that?
possibly because miller allows to use pd's source code in commercial, closed-source applications (e.g. max/msp)
Very probably.
From "http://www.gnu.org/licenses/license-list.html" :
Modified BSD license This is the original BSD license, modified by removal of the advertising clause. It is a simple, permissive non-copyleft free software license, compatible with the GNU GPL.
If you want a simple, permissive non-copyleft free software
license, the modified BSD license is a reasonable choice. However, it is risky to recommend use of ``the BSD license'', because confusion could easily occur and lead to use of the flawed original BSD license. To avoid this risk, you can suggest the X11 license instead. The X11 license and the revised BSD license are more or less equivalent.
So, appart from the possible confusion between the old and new BSD licence, BSD is good choice.
