I Love open source, but I find its really disturbing that some code can't live together when licensed under different open source licenses. Under my Java Code I mostly avoid unnecessary Libraries altogether. That's the reason why I mostly Build my stuff with akka and undertow and postgresql jdbc only (and the jdbc stuff gets replaced as soon as my library async postgres driver does what I need) so that I only have Apache 2 Code (and some parts BSD which will be replaced). Everything else is just too odd. And if I or any other people below me pulls a library in that isn't APL2 i will refuse the PR. It just sucks how aweful it is to write programs with awesome licenses that are incompatible. But you just want to use existing things, which you can't do cause people are dumb and doesn't write licenses which are happy together. I mean why can't I write GPLv3 Code and pull other Open Source licensed things, too? It's still Open. And that's the problem the Open in Open Source mostly isn't open. I see the source, but I can't do anything with it.
