Neil Kaplan's fanpage had him picketing live, he has a few clips of Phil Lamarr and others giving speeches are people rally together:

SAGAFTRA also posted videos on their Facebook from the EA picket line:

DO NOT QUOTE ME HERE, but based on the video I was able to spot a few names that looked familiar to me such as Kaiji Tang, Taliesin Jaffe, Steve Blum, Phil Lamarr, Neil Kaplan, Kimlinh Tran, Sean Chiplock, Crispin Freeman, Joe Ochman, Robbie Daymond, Ellyn Stern, Stephanie Sheh, and Matt Yang King. I am not outing them, I'm happy they're picketing for something they believe in. I skimmed and there was some other guesses, but with all the sunglasses/hats it made it difficult (along with whoever kept the sun in the frame so the back lighting was apparent -shakes fist-).
As for the 25% of all actors things, various articles confirm this number comes specifically from the lawyers representing the game companies NOT from SAGAFTRA or anyone in the VO space. It's hard to say where this number came from or if there's any proof to it (or if it's being thrown around to make it seem like it doesn't matter). Until there's a source or study on this, I'd take this statement with a grain of salt.
Honestly, game devs in some form should have some sort of union. I hope the best for everyone.
