Is there any concrete proof that confirms this? AFAIK the only rights Warner Bros. Discovery owns (at least until December 31st, 2025) are the rights to broadcast FIM on the Discovery Family channel, the series was uploaded to YouTube by Hasbro's official My Little Pony channel, not any of the Warner Bros. YouTube channels. Since the addition of the G4 cartoons to the Tubi and Roku streaming services happened right around the time Discovery Family was supposed to lose the broadcast rights, I would imagine Hasbro brought the streaming rights back after WBD did nothing with them. With the Discovery Family broadcast rights ending in just a few months and the channel on its way out, there's a chance that they'll stop airing it for good and let another company obtain the broadcast rights.
