I'll assume you're joking but I do think Fauna was a lot less tolerant of being told no than others. The newer gens seem a LOT better prepared than Myth+council did, they know more or less what they're getting into and are ready to sacrifice freedoms and doing whatever the fuck for concerts and an instant sub boost.
Aqua was right in saying that things have changed, not because of investors or some other bullshit westoids like to use as a escapegoat, but because Holo is just much more involved in shit now, there's more "homework" and travelling, more logistics, more merch runs and things the talents have to constantly focus on, and that generally adds more bureaucracy. A lot of the older talents probably had different ideas of what they wanted their vtubing career to be, or they were sold on a totally different company. Newer debuts know what they're getting into, they know what they're singing up for, remember that most of myth applied in a time when EN vtubers were expected to fail.
Things change and that is the only universal constant, enjoy your oshis and corpos while they're around and cherish them when they're gone. Nobody in this industry has the right to think they'll stay on top forever or that the corpo they belong to won't change.
