OTOH, the license is optional. You can use it for $0.
I'm not even a potential user of this library. I'm just amused with how people expect open source programmers to work for peanuts.
I'm not expecting it to be free but 5000 usd for just for the right to not redistribute it when you modify the source, seems a bit expensive, but maybe I'm just a poor fella
Why not? If you want to modify the source, just do it in a manner that you can commit back to the repo.
I take you haven't read whats under the title contributions
It's just a standard grant of copyright for contributions to an open source project. Your code will still be available to you under the same license as the rest of it. It just might be incorporated in the differently licensed (paid) version.
You can redistribute your modified source code without sending a pull request.
For comparison, if you choose not to go for the free, public distribution of SQLite, the commercial license and warranty for it is $6000.
Yeah but that's a top notch, mature, well known piece of software. This is a brand new, untested library put together by a one-man shop.
That's the expensive side of the dual licence. The other side of the dual licence is free.
This is an awesome dual license. I like it.
...if you choose to modify the yue source code and not redistribute it.
