The only thing in this that could possibly be "open source" is hazeluff's SVG files for the font. That alone is kind of useless unless it is made into legends that SP can use to make keycaps. These SVG files for the most part, will be "controlled" by hazeluff himself. the money we raised here is to pay SP to make the legends. By default, "we" own the rights to these legends and SP would only use the legends to make keys for us. And if someone wants to use them, they will have to ask us and then if we agree, we give written permission to SP to allow the 3rd party to use our legends (as far as I know from reading other posts here). If we make this truly open source, we would have to tell SP "Hey SP, feel free to make more keys with these legends, or let anyone else to use them. It is free!" I don't think we want to see some cherry looking thin keycaps showing up on ebay or taobao and go, WTF?
What I think we want is, if someone wants to use this font, they can talk to us, we say "who are you again?", " oh sure!", and send a note to SP to let the person use it. With this, at least we will know when we see some random Cherry font keycaps that is thin, we know, oh, it is from our buddies in Korea, they talked to us 3 months ago about using our legends.
