This is incorrect. In general to allow non FOSS plugins you need to use the LGPL instead. If this is something you care about you might consider licensing the main app/plugin in system under the LGPL and the plugins you provide under the GPL.
Hm we like it more the other way around. That the application and from us provided Plug-Ins are GPL and people are free to license there Plug-Ins as they please.
Anyway we will for sure not do any legal actions against Plug-In developers.
Personally, I think it's a shame. GPL generally puts me off as the licence is too complex for me to understand and I don't understand in what situations I can and cannot use it. MIT, BSD etc are simple enough that even without a legal brain I can get the gist of what I can and cannot do.
Okay, but at the end this is not too much about profit.
More to give teachers in the world a tool for teaching Image Processing in a more intuitive way. They anyway will not make profit I guess with ImagePlay.
But if you find someone willing to "donate" enough we might switch license (-,
