The value of open source is that the code is there for anybody that wants to contribute, or fork in case people find its maintenance unsuitable. And even if the project dies, the code remains there for anybody to pick it up later, in case it has value. It has happened before, it can happen again. On the other hand most open source volunteers are unpaid and have no contractual obligation.
So tell me who is the criminal?
The Apache Foundation? But that's silly, since this project might have been simply dumped on GitHub. The few volunteers that tried pushing some fixes since last year? Oracle for donating the project? Speak for yourself in this case, because I'd rather have companies release their stuff, instead of locking it away.
This is an upsetting entitlement complex show here. If you want to contribute, then do so, otherwise GTFO.
