Yeah, I feel like someone needs to write a guide to corporations 'successfully open sourcing a project'. Together with some of Oracle's decisions we have recently had a number of bad examples.
On the other - I'm glad they at least do this when abandoning the project. How many times do we hear "if they discontinue this, they might at least open the source so we can continue porting"? As long as we agree it's pretty much EOLing rather than open-sourcing, we can be glad that we don't get left with binary blobs noone can reuse in any way.
