It's been said several times but ignored - if you want it, buy it. If not, then don't. If you want it without buying it, don't expect Stardock to apologise for being "evil" and give it to you.
I believe that lots and lots of sites have gone to subscription only. Wincustomize would certainly be within their rights to do that as well.
The thing that gets me about this whole thread and some of the negative views is the feeling that somehow Stardock owes you something. If you're a skinner, I respect your talent and effort and happily use and look forward to your stuff. Do I owe you something? Maybe. I've paid for UniverseMetal and think it well worth the price. OTH, some stuff I don't bother to download for free - doesn't work for me. Others might like it, that's fine.
If you think Stardock treats you unfairly as a skinner, take your stuff elsewhere. I'm quite sure I'll live without it fine and I doubt Wincustomize will suffer too much. If you think $20 is too much for a subscription, don't buy it.
In any case, stop your damn whining.
