I can't say there'd be any dramas with a New Site with a 'different political' stance on skinning as a whole.
It's not just about eggs-in-one-basket but more about Stardock, its Admins and Mods being the 'surviving' prima facie 'tutti capi' of skinning.
Once upon a time there were several large and [mostly] independent sites devoted to GUI/App skinning. Most have long gone.
Yes, I can remember it being very time-consuming flitting from one site's forum to another's....just to keep track of 'everything', and at the same time there was a LOT of 'everything' as GUI modding was new to everyone.
But that being said, a new site's different social/political 'bent' would be welcome, most definitely...
