See also what happened with Tron 2.0, where Disney unexpectedly published a software patch 20 years later that obsoleted the community work necessary to get it running on modern Windows 10+. The community was ecstatic, not offended, that the IP owner had randomly decided to contribute. Sure, a lot of their work was either disrupted or nullified, but that's not someone 'ripping off' the community's investment — that's someone validating the community's investment. Given how other companies act, 'validation and cooperation' after a long drought of inattention is perhaps the least likely outcome here. It's so nice to see it.

(Of course, in an ideal world, companies would not be wholly inattentive to older properties — but that's basically unsolvable without economic-level solutions for the problems of capitalism, so I don't have any ideas specific to video games to offer.)
