SAG et al have already more or less abandoned voice actors.

As one who has a spouse who is a member, yup. I think that it’s elitism sabotaging the solidarity. Silver screen actors want to see themselves as better than voice/video game actors so, instead of pushing for massive membership drives and organizing an industry that desperately needs it, they sell them down the river with contracts with AI companies. It’s a bit infuriating. SAG has the resources to destroy non-union acting in video games but seldom shows any signs of being inclined to stand by they colleagues.
