As can be found here, Knowledge Ecology International, the Open Rights Group and Richard Stallman have issued a joint letter to the European Commission asking it to disapprove the acquisition of MySQL by Oracle.
I very much welcome this move. There clearly is a conflict of interest between Oracle's own proprietary database software offerings and MySQL. Sure, the community could always fork MySQL, but at what cost? Potential disputes about the trademark, being forced to rename itself, and confusion among the millions of users world wide (well, might just be hundreds of thousands).
