They might, I don’t know. But I don’t go to the dealership anyway and wouldn’t recommend it to anyone.

Do yo want something like this?

In most vehicles with onstar (Chevrolet mainly) you can pretty easily disconnect the cable that connects the computers to the antenna. You need to install a dummy load to keep it from turning on the check engine light but other than that it’s trivial. Once that’s done, the car will still collect data but it can’t send it anywhere. Just don’t take the car to the dealership for maintenance or they might “fix” the antenna connection for you

It should be noted that the OGL stuff for D&D is included in the free part, along with the ORC licensed rules from Paizo for Pathfinder 2e. I think there are one or two other systems included as well but I’ve never looked at them.
