Sun Microsystems to acquire MySQL

This is probably a concern for the open source developers as Sun is taking over the most widely adopted open source Database Company MySQL. But as per the details in the announcement it will still be opensource. Well, Sun already knows opensource philosophy and quite a good player in it. So my thought goes the way Adobe-Macromedia acquisition. But this is most probably the biggest acquisition ever, not only on the money front but if we think about the clients, Google, Yahoo, Amazon are just the beginning of the client list of MySQL.
