If you're set against the idea of the new subscription plan, there's really not much anyone can do to convince you it's a "good" thing. We know that whenever we raise the price on anything, some portion of our userbase will not like the change. It's just a fact of life. But we have to adapt to things as they change. It's not 2001 anymore.
Unfortunately, we have to cover costs better. WinCustomize, with all of its downloadable content, servers, developers and infrastructure needs doesn't get cheaper with time, especially considering that the site grows more sophisticated with every iteration. When it comes down to it and we have to choose a price hike versus cutting back or restricting services, we chose to up the price, but provide additional content in exchange.
If there are just three skins out of the twelve you like a year, you've already made up the price difference and gotten a "free" skin. We felt this was a reasonable trade-off that would satisfy the largest group possible.
Of course, if you don't like the deal, we won't force you to subscribe. If you're a current customer of any of Stardock's software, you'll continue to get unlimited downloads, you'll just have to deal with web ads. You don't really lose out on the community content, it's just less convenient and you won't benefit from premium features we might add in the future.
Like everything, you have to figure out if the cost is actually worth it to you. Break it down however you like (Zubaz did a daily and monthly cost), compare it against your essential costs, or your other hobbies and figure out what value you might or might not get out of it. Then make your decision.
