This thread boils down to a lot of people thinking Disney can’t do a lot of things because they’ve only ever had experience with
DVC, and other posters like you (and I) who own at places like Wyndham and Marriott, who know that Disney has a lot of room to flex here. Those posters confidently posting “well, Disney can’t do that because that’s against the rules” are likely in for a rude awakening. DVC’s governing docs are very similar to Wyndham’s and Marriott’s. They can absolutely take punitive action against people they deem commercial renters including making it more difficult for them to use their points, temporary suspensions, cancelled reservations, etc. They can also define “commercial renting” however they darn well please and put the burden on the targeted mega renter to bring an action against DVC (and that will not work).
As a Wyndham owner I can say unequivocally that what Wyndham did was an absolutely net positive for the vast majority of owners who now find it easy to book in demand resorts at peak times even without home resorts priority. As with this forum, there was a lot of gnashing of teeth by those with a vested interest in keeping the status quo (*cough* organizations that buy, strip, rent, and sell), but it all worked out in the end.
Kudos to Disney for finally deciding to do something about this.
