It’s really not a quagmire.
When you EOL the game and release the server, just strip the licensed content. Remove the logos. Nobody gives a flying toss anyway.
People want the community and the GAME. They don’t care whether the actual logo is there.
Heck, if the game connects to a community server, have it hide all licensed content. you’ve satisfied your contractual obligations. Whether people mod the game or not to re-add things has no bearing on you.
