Anime VA is mostly non union. I've seen enough Retro Replay eps to have an idea of what Troy has complained about and his time at Funimation isn't one of them. I think he liked the work, but the money just isn't what it should be. I would definitely like to believe he liked his time at Funimation a lot more than he did as a DJ at a strip club or comic con reporter or actor on an F tier Hollywood movie. Dude's best friends with Travis Willingham and Laura Bailey, they all just most likely listened to Troy whom listened to Nolan North who learned where the actual money is.
Oh yeah, I don't think he regrets doing anime as it got his foot in the door.
