Yep. I don't currently have anything published (I did in the past, may do again soon), but if/when I do I'll probably err on the side of “its mine, if you want to update it fork it (but respect the license)”, initially at least, to avoid any issues of ownership should I decide to change terms general or agree specific terms with specific parties.
