First the Google thing, which Google are painting as an attack on OSS when it's probably more an attack on freeloaders ... and now
OpenSolaris getting the boot.
To be honest I don't think it's either a bad move or a big deal. Sun never really gained much traction with the OSS world ... not really ... and Oracle, to me, have a quite clear value proposition: They are a closed source integrated stack of hardware, database and application language/environment/whatever that is ugly, costs and arm and a leg but is hugely reliable and well supported. People who want open can have the Linux x86 world (and heaven knows that's what most of us choose). It's just a question of market positioning and being clear on who you are.
I'm at a loss as to why so many people are upset about all this, to be honest.
Edit: that being said, the future for btrfs has got to be looking pretty bleak right now.
