Here on Wincustomize also still a lot of themes get released. I appears somehow weird.
As mentioned,it's skinner's choice to make/charge a DX "new" theme in WC,the staffs in here can only monitor the contents have no breach broken/involved. Maybe,it should has a policy/banner that informed people the DX has stop developed on its theme gallery,proceeding is your own risk. Yes,there are people clamoring for revival of DX both from the skinners/users. But,on market-wise,Stardock ceased the product anyway.
They could sell an inexpensive "no support"-version or just make it free if it's irrelevant to them anyway.
When "I" stated irrelevant,it meant it was beyond of Stardock's control/responsibility when the third parties (skinners,websites,hosts) still selling/hosting an outdated themes/software. It's quite naïve asking a company abdicate its hard-working property simply due to sale is low or "sell an inexpensive no support" when users always complain even being told before-handedly that it has no support then asking for refunds whatsoever which afflicted both individuals (buyer and developer).
