Wow, just wow
Just when I thought things were positive in this thread...
Just let it go. Not worth it. If he wants to turn this into his own little crusade - let him.
I've had plenty of thank-yous from others (including a couple of the modders) for repackaging their themes (along with appropriate accreditations) when they haven't had time to apply them to beta releases (or preferred to wait for point releases). Some people don't have the expertise or time to know how the mods work - so that's where we all help out. Nobody is out to steal credit from another's creation. This is supposed to be community - not ME, MINE, MY.
Also - some don't have the graphical skills or software to contribute original themes.
Maybe a good idea to poll the original theme creators, and see who is quite happy for us to build on their themes (open source), and who would like to close their themes like HBB.
Personally - I agree with you - I've always regarded our own little community here as better than this.
