En este caso, los de Euro-Office tienen razón. OnlyOffice añadió "additional permissions" según la sección 7 de la AGPL de mala fé, requiriendo que se conserve el logo, pero a la vez denegando el uso de marcas registradas. La sección 7b permite añadir un "additional permission" "Requiring preservation of specified reasonable legal notices or author attributions", un logo no entra en esa categoría según la FSF:
Asking people modifying the software to retain other information, such as a link or logo is fine as a request, but it cannot be added as a requirement on top of the GNU GPLv2 under its clauses covering copyright and license notices.
The GNU GPLv3 Sec. 7(b) does make it possible to extend the requirement, but only to cover items that can be deemed as "reasonable legal notices or author attributions." The terms "legal notice" and "author attribution" cannot be stretched to cover completely different items. "Legal notice" normally means a notice advising a person of their rights or obligations. "Author attribution" is an identification of the natural person who is the author of the copyrighted work. This means that, for example, links leading to different materials are not intended to benefit from Sec. 7(b). Apart from some specific situations, logos are neither "legal notices" nor "author attributions" as normally understood.

Es el problema de la estandarización de las series: los personajes pasan a ser unos arquetipos en vez de unos personajes, y con las tramas pasa lo mismo.
