Streaming availabilities of My Little Pony Friendship is Magic, Equestria Girls, Best Gift Ever and Rainbow Roadtrip are limited -- but why?

By the looks of it, these My Little Pony installments are harder to find on legal streaming compared to all of Hasbro's other shows. Here's what I know so far:

1. The show was once available on The Roku Channel, but it's not there anymore as of this past April.
2. Five of the show's nine seasons are STILL airing on Discovery Family, which really annoys me now.
3. Seasons 5-8 were removed from Netflix, but Seasons 1-4 are still there, and Season 9 alone is on Hulu, which is currently the only way you can stream these seasons.
4. Only two Equestria Girls movies are on Pluto TV. The rest of that series is somewhat harder to find on streaming, especially some of the short episodes on YouTube that were set to private two years ago, and the removal of Discovery Family GO this past May.
5. Best Gift Ever can only be found on iTunes.
6. Rainbow Roadtrip can only be found on The Roku Channel and Pluto TV.

What in the WORLD is going on with Hasbro refusing to release everything G4 on streaming, especially the "Friendship is Forever" clip shows?

If NBCUniversal purchased Hasbro, I could see all the G4 stuff going to Peacock.

I had no idea MLP FIM seasons 5-8 were removed from Netflix. That seems like an arbitrary thing.

I also never understood why season 9 was never put on Netflix. I had to buy it on its own which kinda annoyed me.
