Towa has mentioned that the MV for 'Palette' was paid for out of her own pocket by donations, and has essentially said to keep donating and she'll always give back in similar ways.
In other words, the implication would be that Cover don't seem to financially support their independent endeavours at all, but probably take a cut from them no matter what they do.
For most of them who are comfortably raking in 6 digits a year, getting shafted here and there is probably a necessary evil towards their own end. Unfortunately, this kind of culture also blatantly shows the disparity when it comes to Mel, and as far as the industry at large goes, there was a Nijisanji member begging fans to buy their voice packs so they could put food on the table as they lost their main job as a result of the virus and Ichikara don't pay a salary.
In that regard, it's quite horrifying that the comararderie and hugbox community V-Tubing has fostered is potentially masking an industry that, in some aspects, treats them more overtly as cash cows than the actual Japanese Idol scene.
The one disparity I find vexing, though, is what the fuck Cover see in Aqua to give her a million concerts a month, but knock back a proposed idea by fucking Pekora of all people. Surely Aqua's corporate, vapid spreadsheet data on the screens of middle management isn't so much greater and awe-inspiring than what Pekora gives to the company too.
