Yeah, it mirrors Netflix buying Millarworld as a hedge against losing comicbook derived content. Now that Disney is making their own children's streaming service, Netflix might want its own children's content factory.
That's especially more true now with DreamWorks owned by Comcast, there's no guarantee that Netflix will have access to children's content in the future if Comcast wants to have its focus on its own streaming initiatives.
I could see either Comcast or Netflix as the most likely buyers; the two are in a relationship now due to the DreamWorks-Netflix deal, but if Comcast wants to go in a different direction with its own streaming initiatives in children's content, then having DHX's properties is a strong supplement (and conversely Netflix would need that if it lost a lot of its children's content to Disney and Comcast going for their own services).
It's worth following what happens to DHX for that reason alone. Apparently Peanuts US theme park rights are licensed to Cedar Fair through 2025 with an option to extend that to 2030, so that won't be available for a while even if DHX is bought.
