Oracle’s has a new tiered pricing model for MySQL. First on the list: InnoDB requires moving from the free “Classic” edition to the $2000/year (for up to four sockets) “Standard” edition.
Now all Oracle has to do is find a way to charge people for the privilege of dropping MySQL in favor of Postgres.
Full, non-supported releases are available as the “Community” edition.
Did MySQL have a contribution copyright assignment policy? Will Oracle be able to create a proprietary fork of MySQL, or are they bound by the terms of the GPL?
