Knowing everything we know now, it makes sense why Sana graduated.
>Council had the absolute worst management in EN history that had heavy hands in controlling their content (when Myth debuted, there was only two managers for everybody so they were basically left to their own devices)
>Sana had her projects constantly discouraged, shut down, and denied (i.e. the Holoscope streams, Kusoge Monday, "variety" streams where she just does a lot of stuff in one go)
>Did not want to draw at all due to being extremely slow and unable to focus while talking; was heavily pressured by management and Sanalites to do it anyway despite clearly stating her discomfort
>Dog died during peak of COVID in Australia -- for those who don't know, Australia required a three-week confinement period in assigned apartments when entering during this time -- which becomes the basis of tons of direct shitposting both in her chat and everywhere else
>Ends up in an accident, hurting her back
>Can still draw and stream while laying down, but was denied PNG usage by management
>Ends up leaving because this shit sucked
tl;dr
>Management was denying Sana's ideas and heavily discouraging the ones she did without permission
>Management didn't assist in fighting against shitters in her chat causing a lot of spam
>Management blocked Sana's wish to stream with a PNG
>Management pressured Sana to do drawing streams, which is the one thing she absolutely hated doing
This is why her graduation notice said it was due to a difference in content ideas and not her health issues. Her health issues, while bad, weren't life-threatening and was on the way to recovery.
It's just that the way everything got handled by management was complete shit, which was corroborated by Mumei who said she almost graduated too back then until she got a talk by Ina; Kronii losing her god damn mind back then until Mori stepped in, and IRyS absolutely losing her shit over how fucking trash management was in general (causing redjuice to be unjustly targeted because it was believed he was the reason for a lot of the problems, only for redjuice to comment about how he never received any correspondence from EN management unironically months after her initial complaints about her redesign being late).
Thankfully there was a complete overhaul of management, so if Sana were to return, she'd probably thrive instead of being disillusioned.
