On the off chance that this isn't niji 2% deflection bait, I'll make an effortpost from my perspective as an ex-teammate (currently a joshu-kun)
The kneejerk response from this board will be the Tempus collabs, but really that was just a reflection of how she's changed for the worst over the past two and a half years. Mind you, she'd never been perfect, but her most obvious flaw (her gamer rage) was at least endearing. But starting in 2021, she definitely started to lose interest in things--coming up with new ideas and then dropping them after a session or two and making schedules less frequently (eventually stopping entirely, though recently she's been scheduling more streams in advance which is a positive step). This was a gradual process with ups and downs, and for a while it was more than forgivable because her streams were generally enjoyable, her members' content was (and still is, from what I've heard) solid, and her la creatividad projects consistently delivered.
During this time, her relationship with teamates was starting to change. She was never really "GFE" as they so often claimed, but she had a genuine approachable girl-next-door vibe and her openness to discussing her past made her that much more genuine and endearing. She knew that a lot of her fans had dealt with or were dealing with some of the same struggles of loneliness, depression, and poverty. She was genuinely grateful for their support and, while still wanting them to make better lives for themselves, still understood and accepted how many of them used her as a parasocial emotional crutch.
When Tempus debuted and she decided to actively promote them and leave herself open to collabs with them it shouldn't have been a big surprise. She was obviously a big fan of the Holostars from the beginning, and like Fubuki wants to see all of "HoloPro" prosper. At the same time, she knew full well the audience she had cultivated and passive-aggressively told them to fuck off, this time wielding her belief in "self-improvement" in an entirely cynical and self-serving kind of way. She didn't handle it nearly as stupidly as Kronii and so got overshadowed, but it did leave a bad taste in my mouth, though I didn't actually drop her until she formally announced the Worms collab. And the real problem was that this came at a time when EN was stagnating, when Ame had lost most of her enthusiasm for gaming or projects, and when she was streaming less and less with other Holos. Gurame and Iname were dead. For the past eight months or so she's basically continued that stagnation--the Tempus collabs were ironically very infrequent, but her other issues remained and for the most part haven't gotten any better. Like most of Myth, she's phoned it in and is only surviving off the inertia of her golden era from late 2020 to early/mid 2021.
