Every programming language I've ever used has been open source. I have fixed small issues myself, and I know that I or someone else could fork them if the current maintainers quit. Whether developers have the right to the source is debatable. But personally, I wouldn't stake the life of my projects on a language (or database) whose life depends on one entity and their business model. And it seems to me that others feel the same way, and that the trends are toward OSS - .NET went open source, Oracle is giving way to PostgreSQL, Azure now supports Linux, etc.
