This is the crux of it, a lot of people talking about IP ownership
genuinely do not get it. When you're trying to run a sustainable corpo without putting yourself in a hole doing so, there will be times where you have to be the bad guy. That's the reality of the situation; making everyone feel good all the time does not generate revenue, at best it makes your corpo a stepping stone with no identity of its own that talents use to buy time while hoping they get into VShojo one day, at worst it bankrupts you while your name is dragged through the mud because the people you were trying to please all had different expectations.
A good business arrangement is one that is mutually beneficial, which corporate vtubing is. The talent has their upfront costs (model and rigging etc.) paid for, and is marketed to an audience that likely wouldn't find them otherwise. The corporation builds up a portfolio of intellectual property which holds value, and opens more opportunities for them and the talents signed under them as a whole. This is agreed upon, and if both parties willingly signed the contract, it can be assumed they were both on board with it. It's a glorified work-for-hire in a way, which is not dissimilar to how most of the entertainment industry functions.
The "holding value" part is important even for corpos on the verge of closure, because there are likely still outstanding costs, and it's not like they can pay those off with the revenue share or sponsorships if the talents are no longer streaming. It's the vtuber corpo equivalent of a sole trader selling his car to pay off a loan when his business goes south, you need to find cash somewhere, and selling your assets is the easiest way to do it.
But the problem is, the loudest voices in this discussion are teenagers who have never had a job, let alone owned a business. Their idea of right and wrong is decided entirely by how things make them feel, rather than whether they work in practice - and if somebody gets upset at any point it's obviously the big bad CEO abusing everyone (even if the guy's severely ill and
one of the talents affected isn't too bothered by the IP cost since she understands the CEO invested a lot of his own money into funding it). Indies can jump into the discourse to push their anti-corpo rhetoric because appealing to emotion is much easier to package into retweet-bait for clout than nuanced breakdowns of a company's financials and why things are the way they are, and then those same people will act sad all over again the next time another one of these Twitter-friendly "we keep nothing and give you everything" nothing-corpos falls apart after six months.
