That company ruins everything it touches.
Look what happened to MySQL, leading to the need to fork to MariaDB.
Look what happened to ZFS; as soon as Oracle got its grubby mitts on it, it closed-sourced all future updates and made it incompatible with the open source version.
Do you use Solaris? If you do, I don't even have to write anything here. Support has gone absolutely to shit since the acquisition.
And now Virtualbox is stagnant and uncared for.
Why is anyone surprised? Oracle bought Sun and ruined everything awesome about the company. It was the absolute worst possible company that could have acquired Sun, and it shows in every way.
Fuck you, Oracle. With a turbo-charged chainsaw, sideways.
