The most of are repost are open-sourced with MIT licence. It's clear now, that the way we put words together in the license for clients is not clear. Our idea is straightforward: if you want to use the software, you can do so for free, whether for personal use or within an organization. However, if you aim to sell it for profit(like change the logo and put price tag on it), you need to contribute to its creation in some way; this is why permission is required. At least, that's the case at this early stage.
