I don't always agree with Monty but this time he is right. Now is the time to provide feedback on the merger. I wish there were more commentary on plans for MySQL after the merger.
My concern is the documentation license. If we want to improve MySQL at a faster rate than the docs copyright holder, then we must create separate documentation as we cannot publish a modified version of the official documentation. Several people have written about this before including me, Baron, Sheeri, Arjen and Justin.
Despite comments on stage between Karen and Kaj at the User Conference, there have been no changes to the docs license. The lead for the MySQL docs team explained to us that there will be no change and he deserves kudos for his bravery. I am very disappointed that neither Karen nor Kaj have said anything on this topic since then.
What else can you do? Find a different community. Check out the activity on the Drizzle mailing lists. I don't participate in Drizzle but I lurk there and am extremely impressed by the activity on the mailing lists and the changes they make to the code. MariaDB has yet to become active for external developers but it is quickly gaining momentum.
