all Extensions have to be under the GNU/GPL
Well, I am not so sure about this, especially when it comes to paid Custom Work,
and I have not found a written statement from OC, requiring this, anywhere, so far.
But strictly from the standpoint of a Dev, it's at least understandable, that one tries,
to keep one's work from beeing taken & re-used by others. Especially when it comes
to OC, the probably widest spread Darknet Code in the whole world.
And other Extensions exist, for some time already, requiring users, to add some Code,
to call external Servers, in order to function. So, where does it start, and where does it end !?
But it looks very professionally, and it's all done very professionally, one could even
get the impression, to visit an 'official' OC Extension Site. And this would, if I would
care about, worry me more, than just a coded Mod...
Just to make this go away from the unanswerred Section ...
