Oracle and MySQL -- Good Move or Bad Bet?

sendai-X writes "With the recently announced purchase of Innobase, Oracle has shown it's intention to further support open source. This is key as open source enters the mainstream in business and in light of the success IBM has had with the Eclipse project, and Sun recently looking at purchasing PostgresSQL. What do Slashdot users think about this merger? Is it beneficial to the market and database users by having the largest database vendor openly support MySQL and provide an upgrade path to Oracle? Or is it just another cog in the Oracle machine in their attempt to dominate the enterprise IT market? Will this change the database market landscape? Will it help or hurt IBM and Microsoft?"
