Because there's only like 10 VA in the whole of the US, right?
Allegedly it was a pretty shitty place to work with.
But since this isn't a wrongful termination or hostile work environement lawsuit this has nothing to do with the subject at hand.
I'm a little confused by your reaction, so I'll try restating.
Short version: A portion of old-school Funimation haters (extreme subtitle fans/fansubbers/dub purists) from two decades ago are probably using Vic's lawsuit as a way to signal boost anything they think can hurt Funi's relationship with Toei, not necessarily caring if it helps Vic at all. The ISWV crowd is probably just lashing out with whatever they can get their hands on, and the Funi haters are the ones that have the straws to grasp.
Shorter version: Some Dragonball Z fans used to really hate Funimation. Apparently still do.
To be extra clear: Lots of reasonable people dislike Funimation for plenty of different reasons. I'm just referring to the unreasonable haters here. :)
Losing Funimation would lose a major publisher of home media distribution, not to mention a lot of other things.
That's what some are hoping for. Funimation loses the license, the fansub justifications go through the roof. There's definitely a (very) small crowd that would be thrilled if all the anime localizers went out of business tomorrow and everyone went to fansubs and became more niche. I was seeing complaints on twitter just yesterday that Crunchyroll made anime too accessible and they longed for the old days when it was much harder to get.
