No, actually, it's pretty simple.

There is (as likely as not) NO issue with the server.

The issue is that the CLIENT software is unavailable in other than GPL
and other "private license-for-money" forms.

In order for you to use MySQL, you have to link GPLed libraries in
with your code.  There are no LGPLed libraries; that would break MySQL
AB's business model.

There is considerable unhappiness surrounding this vis-a-vis SAP-DB;
SAP AG had had the server software GPL-licensed, and the client
software licensed under LGPL.  Along with renaming it "MaxDB," MySQL
AB is apparently eliminating LGPL-licensed libraries, which is causing
some consternation in the user community.  Which will probably point
some system integrators over to use either Firebird or PostgreSQL...
