Thank you for taking down the repository, you seem to have taken this very personally which was not the intent. As I originally said I'm flattered that you liked the theme enough that you wanted to port it. And wanting to contribute to help others is admirable but that doesn't change my stance on this.
If the time comes that I no longer wish to continue work on the theme I may change the license but while I'm still actively working on and updating the theme I don't think I'm being unreasonable in asking that modified versions not be shared.
It does seem that the majority of regular users here and on the Recalbox forum are very respectful of anyone who contributes to the respective projects and certainly I don't know of any regular users here who would knowingly step on anyone's toes by creating derivatives of another's theme without getting explicit permission first.
I really don't like this kind of confrontation, it's a real downer.
I'd just like to say thanks to everyone here who shows support for my work, I appreciate it and it does make the effort worthwhile.
p.s thanks @LiveFastCyYoung for sticking up for me.
