MySQL is GPL correct?

What a coincidence! I just got started on my anti-GPL rant in my last MySQL-related post. Here's the deal:

* MySQL <4.0 can be used gratis by anyone because the C client library is LGPL'd.
* MySQL >=4.0 can be used gratis only in conjunction with GPL'd software since the C client library is GPL'd.
* As of quite a while ago, the server side of MySQL was GPL'd.

The same is true of the new JDBC drivers; MySQL AB purchased the MM.MySQL drivers (now MySQL Connector/J), and changed the license to the GPL. This is all part of a concerted push to force commercial users to buy commercial licenses. I'm sure Richard M. Stallman thinks this represents progress.

You can use the old C libraries and the MM.MySQL JDBC drivers with MySQL >=4.0, but you won't have access to any of the newer features.

I verified all of this with the MySQL AB sales department -- minus RMS's opinion -- when I first noticed the licensing change with 4.0. It was for this reason, as well as some technical ones, that I switched my development to PostgreSQL, a properly (BSD) licensed application.
