Nah. The anti-advertising clause is essentially designed to prevent you from
saying "OpenLayers Endorses This Site For All Its Awesomeness!"

Legally speaking, you're required to give some credit to OpenLayers in your
documentation, or in the OL.js file itself (which is why the build tools do
that for you); so long as you include those notices, and don't try to say
"The OL Devs said my website is the most awesome ever", you're all good.
