MySQL professional here. I'm quite pleased with Oracle's 5.5 and 5.6 releases, and feel that they're doing a pretty good job. While they've not been perfect stewards, I feel they have done better than Sun -- perhaps you don't remember the fiasco that was the 5.1 release?
I don't feel that this is a trollish opinion. Mark Callaghan, a MySQL luminary who has done a lot of excellent work for the community also has positive things[0] to say about Oracle's stewardship of MySQL.
