Sun, MySQL and the return of integrated solutions

Post in ZDNet mentions Firebird. Check the excerpt from the full article:

There are many open source projects that offer respectable database technology including Axion, Firebird, MaxDB, PostgreSQL, Ingres and quite a number of others including an old friend, MUMPS (I was a software engineer at a company that created MUMPS-based solutions in the late Jurassic period)! If Sun tries to “squeeze” the users of MySQL, it is likely that these organizations will simply move to another platform and say goodbye to MySQL and Sun. Do you agree with my line of reasoning?
