Requirement 1 of the DFSG is: Free Redistribution The license of a Debian component may not restrict any party from selling or giving away the software as a component of an aggregate software distribution containing programs from several different sources. The license may not require a royalty or other fee for such sale. The mysql license restricts the distribution of mysql if the aggregate distribution contains non-GPL software. DFSG #1 does not allow for a distinction between free and non-free software among the "components of an aggregate system". Neither does the GPL make such distinctions. The "Commercial use for everyone else" term is either (1) completely incompatible with the GPL, or (2) completely circumventable, since if I received MySQL sources under the GPL, under section 2.b. of the GPL I have the obligation to use GPL (with no MySQL AB additions) for any third party I distribute to, for any purpose. So I put my noncommercial GPL sources for MySQL on my noncommercial FTP server, and anyone can download and use them for any purpose, commercial or not, solely under the terms of the GPL, because the GPL is how I got the source from MySQL AB. In any case, it's a stupid, self-inconsistent license and really needs to be changed immediately.
