I’d vote to force them to do one of three things:

1. Open source the whole game.
2. Release the server components in a way where anyone tech savvy could grab them and spin up a server the game client can actually connect to.
3. Make the game offline only (obviously impossible for many games these days, but…)

It should be forced upon them. Want to sell a rug pull? Get ready to not own the rug pull.
