Both the "fired for low productivity" and the "Ina's nepotism hire" rrats are ridiculous.
>fired for low productivity
Ayame is a thing.
There has literally been zero examples of holo chuubas getting fired for streaming too little.
Sana's supacha revenue is only slightly lower than the green whore and the owl slut despite streaming half as much.
From the Cover's standpoint, Sana doesn't take away any resources that'd be better spend elsewhere. Even if she pulled a Roa, it's much better to leave her be than fire her - especially right after the Rushiagate. Also Sana's PL being known actually helps the Cover's reputation in that case.
>Ina's nepotism hire
Ina is too smart and selfish to pull the strings to bring her friend in a new gen before accumulating enough reputation and experience in the company, especially if said friend doesn't have a substantial streaming experience.
The friendship with Ina *might* have influenced the management - but again, that's not Ina pulling any strings, that's just lacking better candidates.
