Except they neither gain nor lose anything by licensing it for free. They aren't paying for the servers, they aren't paying for developers, community managers, support staff, etc to support the game. They don't really have any financial incentive to shut down Homecoming even with declining sales unless they think that the game would generate enough profit so as to change that for their investment in all of the above, for let's be honest a niche, (almost) 20-year-old game. Could they shut it down? Yep, they own the IP. Will they shut it down? At least not in the immediate short term unless Homecoming messes something up and breaks the license terms. Longer than that, say at the end of the terms of the agreement, we don't know there. Hopefully, they just renew the terms for another period (however long that may be) because there is still really nothing to lose or gain by doing so.
