Yes, you're right, the legal stuff sucks. We wanted to make it as simple as possible and not have 100 pages terms and conditions. We will try to make that more clear so people can understand that if they get this product for Free can be used by how many devs they have, in how many products they want.
Our business is to create good looking products that speed-up the development for web developers and not to go after people who use our products without a license. Probably there are 1000 people every day who just "View Source" of the page and get the product. We cannot and don't want to focus on those people :D
