So long as you make the MySQL ODBC driver source code available, you
have no problem. The GPL infection kicks in at the step where you
link, which you're not doing when you ship that driver.

You're smarter than I if you've figured out what motivates Stallman
and Moglen, and the text of the license is far from clear on this
matter.

This business about incompatibility between libssl and the GPL seems
somewhat more plausible. Ideological opposition to shipping GPL
software is also a plausible reason. There's nothing wrong with any
of this. I just don't find the stated reason terribly plausible.
