Let me preface by saying that the whole "comparing to Jesus" thing and asking to boycott the game is super wack imo. I do understand her plight though and the pain she exhibits is one I've lived and seen so much in the creative industry. Where everybody just thinks you should shut up and be grateful you earn so much per hour while the truth is way less happy.
I think a lot of people don't really understand how the job works and judge it wrongly based on assumption. Comparing it to working with a full time job isn't how it works. I've worked with nearly a hundred VAs in the past and it's a very odd occupation in terms of working hours/shifts. You don't just wake up and go do a 9/5 and earn 400$ per hour.
On the surface it's one of the best paid jobs you can do that's low weight and effort. Obviously there's a ton of bad VAs but they generally get snuffed out fast (annoying to work with, lots of recording sessions needed for a good take (which means more work in the editing room), less control of voice). What you're left with is little work that's left for a ton of VAs all fighting for work.
Most VAs I worked with had maybe one or two recording sessions per month, sometimes each one lasting 4 hours in total. Sometimes they had less, one per month or quarter. That's what they had to live off of. And now you're thinking " damn, only working 1 day a month, that's great". That's not how that really works. Most are working day and night, sending out portfolios, fighting on social media for attention and it's pretty rough to find work. Calling clients. Doing intro meetings. Researching clients, calling them up "hey I saw you were working on this project, need a VA"? Others that don't do this are either broke or pay for an expensive agent which means they need to earn it all back. Most that I know work weekends on the side (cafe, restaurant, or some are stage actors/writers).
The 'golden egg' is often considered to find a 'character' that you become. Sean Shemmel famously became Goku and he never had to work a day in his life anymore. He'd always get the Goku role. Commercial featuring Goku? There's his voice. Toy that says Kamehameha? That's his voice, royalties here they come. It's the equivalent of being a famous writer or artist - your life is now paying for itself. Only very few reach this point and it's a part they try never to let go. The guy who did all the movie-commercial voices, Goku's voice, Mario's voice - they're set.
There's currently quite a controvery going on relating to this vanishing in favor of hiring Hollywood actors (and paying them by the millions) for more recognition (i.e. Mario by Chris Pratt). So voice-actors are already in quite the pickle regarding this. It isn't a field that's taken for granted and often thrown to the side. Games famously just were voiced by staff to save costs, and it's one of the reasons why MGS took off (actual professional voice actors were used). The job is taken a bit more seriously today, but not a lot and it's still the first thing to go.
Helena is, looking at her portfolio, not the most succesful freelance VA. She's had a few gigs and a lot of uncredited commercial work until she got a gig with Bayonetta. Regardless of the series, it's a pretty nice job. Voice-payment goes by royalty in general since you don't just record the voice, you pay for the right to use said voice. If I make a drawing for a company, you buy to use it for a website, but if you want to use it on TV you have to pay me royalties every time you air it - that's simply the law.
Bayonetta got quite a few re-releases, she got released in Smash, there's a film. Chances are she made a small living off of those royalties while doing some uncredited sidegigs on the side.
The offer made by Platinum/Nintendo was a flat 4000. No royalties. A total buyout. And this is before Taxes are applied (so about 2500 left at best). It's the type of payment you'd offer a rookie VA who is out of his depth and abuse his unknowingness of the industry. Why they did this is beyond me. They clearly had the budget, since they're paying every Youtube a flat 10.000$ for covering the game (insanity, now that's dumb imo). So it's either that they want to get rid of her but had contractual problems, or there's more going on (hard to work with, internal issues, hell could even be she was shagging Kamiya, who the fuck knows).
Looking at her, I do feel she was dumb. From the feelings in the video I feel like she thought Bayonetta 3 was going to be a big payday, and adjusted her spendings accordingly before seeing what was up. So I'm more in support of the whole VA's plight thing (being replaced by Hollywood, underpaid etc.) than her specifically. After this video she's dead in the water. She broke an NDA, did massive reputation damage - she's probably going to get sued into the ground and no agency will ever touch her again. It also had the opposite effect: Bayonetta 3 preorders skyrocketed after her video and it is sold out now in most shops.
Regarding "then just stop buying games": we're all typing this on machines made by child labor. Wearing shoes made by child labor, that were shipped by staff that die on the workfloor to get it to us. Half the food we eat is from exploited slaves. You can't take a stand against everything. But then don't shame people that finally at least take a minor stand once in their life for not doing it against everything. One time is better than never I'd say.
Personally it reminds me a lot of working in that one animation studio where we all slaved away for a meager salary while our managers made millions but "you should be grateful to work in the industry". Fuck everyone for telling me that back then. Ruined my fucking life for years.
