The problem with Funimation settling is that Vic gets to set the terms of the settlement. As pointed out, the court can't order Funimation to spam 'SABAT IS A RAT' on their twitter and then do synchronized hop circles outside their building, but a settlement can include that as a part of it. And since everyone basically knows you can demand anything in settlement, simple apologies will mean less via settlement than the court proving they're liars. Also, Vic isn't interested in humiliating them.
Terms of settlement will likely include:
All relevant discovery that can help in the civil conspiracy and lawsuits against the others.
Renewed contract with Vic restoring his previous jobs and ensuring he will continue to voice act (this is very important to Vic)
Some kind of assurance they won't commit further TI with conventions, like revealing info on those who orchestrated that
Flipping on Sabat
Using their connections to restore his relationships with other companies they intentionally poisoned
Terms they could include if Vic is feeling vindictive:
Severing their business relationships with Sabat, Rial, Marchi and co
Giving Vic a more Sabat-like role in the company going forward
First pick on choice roles for new dubs
Publicly publishing embarrassing information or statements about the conspirators
Funimation personally running a PR campaign for Vic to help his reputation
Thus, while it's more expensive to keep fighting, there's some reasons why Funimation might choose to be stubborn and burn through money and goodwill instead. If they lose the case they'll be forced to pay Vic millions, but they won't be forced to employ him. If they settle the case, they may be forced to pay less, but they'll probably be forced to employ him again. And burn a lot of bridges with the people who got him fired in the first place.
Come on, that dub is pretty shitty in terms of dialogue. I can't deny that all voices are done quite well, but I think J. Michael Tatum did a pretty bad job at writing the Steins;Gate screenplay. On a side note, why do all of these people have the first initial thing going on? J. Sean, R. Bruce, and J. Michael to name a few.
I'd argue while it's a poor translation, it's a good localization. Many terms were changed in it, but it was primarily to change the style of characters from 2ch/netizens to 4chan/gamer nerds. While not faithful, that meant the intention of the writing (and the characters being identifiable/recognizable as online-savvy loser kids their age) was better preserved.
