Thank you for your feedback. Could you expand on your first point, I understand the idea of a dropdown being wider, but I didn't understand your use of the term oneliner.
Your second point is too general for me to understand what action might be taken and I am not familiar with the term PACR.
With reference to your last point, the source code to Moodle is made available freely under the GPL license and you can install and run it on your own machines without any financial cost and without any advertising component. Could you indicate which clause of the GPL you are concerned is being breached.
It is possible to pay a very modest fee to remove the advertising from the MoodleCloud service. I am not aware of the EU restricting the ability to use advertising as a way of supporting a web based service and would be interested to know what you are referring to.
