Thank you for the detailed explanation. We have over 1 million users who checked our resources, 97.000+ web developers are using them in 150.000+ projects and this is the first time when somebody is not happy with our licensing options. We will see what we can do in this area.
Given the number of questions on this HN page about licensing I think it's a mistake to conclude my comment is the first time someone wasn't happy with your licensing (And people who pay for software tend to be the same people who care about licensing, so the fraction who care about licensing is likely to be a much higher fraction of potential paying customers than simply x/1.000.000)
How about just offering it for sale on envato under their licensing. Yes, you give up a bit of revenue because they take a cut but you don't have to pay a lawyer to draft a license for you, and you can still offer it on your own page under your own non-professionally-drafted license at the same time if you really want to do that too.
At any responsible business with 100+ employees, third party software often passes through legal if it doesn't adhere to a pre-existing license(apache, mit, etc.). I think it wouldn't be correct to assume that there are only a few people concerned with licenses, especially because no license means all rights reserved, and you guys are pretty close to "no license". There are excellent licenses to choose from, and some already seem to fit your needs(as you describe them).
On another note, I personally see a license as one of many signs of product maturity. If there is a well established license in place, then that tells me the product is likely pretty stable and this along with other factors helps me determine if I should make the time investment to try and use that product. I think the issue here isn't whether your current users are having any problems with your license, but rather there are likely potential users who haven't even touched it because of the license. Having an explicit license is very helpful in the long run.
