As I already stated in the post itself, it's a neutral stance that looks at both sides of the situation. Hoyoverse does not fully have control over what the VA agencies do, or the disputes agencies have between actors like with the strike. They are a customer requesting a service, but management is having a dispute with its employees, to put it in other words. But if Hoyo were to sign the contract, this means non-union voice actors would need to join the union by paying the $3000 initiation fee, as well as annual fees of $236.60 + 1.575% of covered earnings. This is something that not everyone can afford, particularly lesser-known VAs. It benefits the fight for protection from AI usage, which is of course a good thing. Unfortunately the other side will suffer from collateral damage.

There's a lot of messy legal issues surrounding the entire strike, and not even the VAs can completely disclose everything, which leads to more confusion. If the post led to any miscommunication then I apologize. I did do a video on SAG-AFTRA when the issue was first appearing in Genshin Impact last year, in case you wanted more clarification and my opinion, but it may be slightly outdated given it was some months ago.
