Please stop wasting potential customer's time by offering a great looking, professional-grade product with a horrible, non-professional license. I'd love to use your templates in my business. The pricing is on the high end of what I'd pay but not so high that I'd walk away. But I have to walk away,I can't allow myself to waste any more time looking at your site because the license is an absolute deal breaker.
Licenses aren't just "ugh, we do software but we have to put up some stuff about licensing." Licenses are essential to any form of commercial software. If I base my front end on your bundle, which I paid for, I'm basing my business on your bundle. If I don't know what I've bought and what I can and can't do with your bundle, I don't know what I can do with my business. That's an absolute deal breaker. There's a reason why licenses look the way they do. This kind of stuff is incredibly hard to specify and the evaluation criteria isn't "I'm a programmer and I think I know what it means" it's "I'm a court of law reviewing how licenses have been interpreted historically for the past thousand years."
Did you pay a lawyer who specializes in software licenses to write that license? If you did, find a different lawyer. If you didn't, take down the license and your offer to let people use software you don't know how to license until you have found an actual lawyer and had them draft an actual license that is as professional as your product.
If you want a plain-vanilla license out of their law firm's files, expect it to cost a few thousand dollars to have your license prepared (mostly for the time it takes them to understand what you want). If you want an unusual or highly customized license, expect it to cost more like five to ten thousand dollars to have it prepared (because they will need to bill you for time spent writing that custom document). Licenses are hard. They are literally the contract between your business and your customers' businesses. They matter.
If you had a real license, I would have bought a pro license this morning. You don't, so all I can do is complain about it on hacker news and hope in some future life I find your site again and find a decent license on it.
