While it seemingly looked like a response to this petition, William Joyce recently said to the fans of the series:
"The real victory was how people loved the show then and now. The fanbase has stayed fervent. The show still airs on Disney Plus".
He suggested to his fanbase that if they want more episodes of Rolie Polie Olie - they must spread the word and let Disney know about the petition, which in turn got a positive response from most of the show's fans (which is coincidentally similar to one of the petition's goals):
We should too spread our voices for this petition further by reaching out to fans of the show to let them know about this petition, and give them the opportunity to sign and share the petition. That way, it can help allow us to likely reach out to Disney to let them know that new and older generations of fans continue to enjoy the show to this day in order to finally greenlight/approve the show's reboot to give William Joyce and his team to make new episodes on Disney Plus soon enough.
