>>1168578821- The Loud House has gotten seasons and episodes that surpassed Sponge Bob. Twelve Forever was a minor hit, not worth investing on.
2- The team behind Loud House is bigger than the team behind Twelve forever. It would have been much harder to disband.
3- Loud House became quickly an integral part of Nickelodeon, and (to a lesser degree than Sponge Bob but still very high up there), it's the face of the network. Nick spent a lot of money and energy separating the scandal and the creator from the perception of the show. Nick without Loud House, specially as an abrupt change, would look weird. Branding is all, and Loud House couldn't be cancelled without harming it. Twelve Forever isn't anything close to the face of Netflix, it's just not part of the Netflix identity and branding. Even if you love it, for Netflix it was just another show.
4- Loud House is a cartoon running in a network of cartoons, while twelve Forever is a cartoon on a streaming service that can afford to cancel minor hits because they cover all kinds of shows, without dependence of just one genre. To save Twelve Forever, another company should pick it up, but, who would?
Could it be saved? Sure, but although it was meant to be the new Steven Universe and the new Adventure Time, it was neither and the brand is now rotten. To save it, someone with a lot of money should care enough, and whoever has that money already knows it's way smarter to invest in a new cartoon. Twelve Forever is done.
