This is the wrong way to look at it from a business perspective. They don’t directly profit off licensing or support or anything like that, but they gain free advertising.

They gain absolutely nothing by handing over the name and brand - in fact they lose valuable brand recognition.

Obviously most people in the industry hate them with a passion (see this thread as evidence), but many see the association as evidence that they might at least have some expertise with that product set. I certainly don’t agree with their position, but it makes sense commercially.
