From the last paragraph in the article

Paramount and South Park‘s creators have signed a $1.5 billion USD deal for the licensing rights to the series. This includes the rights to exclusively stream both its classic and new episodes with Paramount+ for the foreseeable future, and an agreement to release ten new episodes a year across the next five years. With this deal just beginning with the premiere of Season 27, South Park is likely not going to end anytime soon.

So, no... it isn't.
