...why this is such an issue. I know that MySQL is distributed (at least to some) under the terms of the GPL. I have received it only under GPL2, and never under their proprietary license.
The GPL has been applied to the MySQL code, and it cannot under any circumstances be removed. Sure Oracle could absorb whatever code they wanted into any proprietary product, but I still have GPL code, we all still have the original.
Development could continue in the community, we can still enjoy the benefit of the MySQL database with or without oracle's blessing. In short, this a non-issue because we will always have the database code as it is now.
The fact that Monty is a prick and a sellout makes no difference either. PostgreSQL won't be sold out, and even if it was, we would still have the GPL'd versions to fork from. That's what the GPL is supposed to do. It is there to protect us from the Monty Wideniuses of the world!
