Found it:

It is better than it used to be where it really pushed commercial
license for commercial use, but they still have:

Please note that MySQL AB can only give advice on which license is right
for you. The final judgment, of course can be made only by a court of
law. With that said, we recommend the commercial license to all
commercial and government organizations. This frees you from the broad
and strict requirements of the GPL license.

To anyone in doubt, we recommend the commercial license. It is never
wrong. Thanks to our cost-effective way of producing software, we are
able to sell our commercial licenses at prices well under the industry
average.
