I don't think you can change the license of existing code at all, unless you're the copyright holder. Best you can do is release someone's code as part of a work under another license. Anyway, > It is also bizarre that someone could take BSD code, make trivial modifications, and now such cannot be sent upstream or used under the original license. That's the case for anyone taking BSD sources and turning it into a closed product, isn't it? Even if you get the BSD-licensed sources, the trivial modification will not be upstreamable. That's kind of the entire point of permissive licenses, as opposed to copyleft, isn't it?
