CP, well actually this can go for the rest of you accusing Romito as well;
First off let me say I'm a huge fan of VisualV, I use it currently as it's not as resource intensive on my gaming rig. It does what I want it to do without changing anything else, which is all user preference imo. That said;
I'm not on Redux's side on this issue, or yours - but just because someone other than you finds that these settings look the best, automatically makes those values your own work? I mean, sure it took you time to "find" those specific values, but did you think for one second that Romito also took the time to find values/settings he also thought looked the best?
You're basically accusing him of stealing "files", but in reality are VERY small portions of code that represent a fraction of all the work that both you and Romito did. How do you even know he "stole" them, did you ask him? Were there leaks of info that he "said" he did? So what if he used a "portion" of your work, is it copyrighted? If it is indeed your work, the least Romito needs to do is contact you privately and explain why the values resemble your work so closely or apologize for any copied work and move on (or you PM/DM him to find out, nicely). I'm really disappointed that you would post here first and make outrageous accusations towards a hard working individual that put hundreds of hours (I'm sure) into creating this mod for us all. If you did get confirmation that he "stole" your values, then the rest of this adds to the above. Make sure you edit the original post, though - or post an update, video, anything...
That said, deal with this privately - gossip and rumors are very tough waters to tread and will create a lot of unnecessary backlash. If someone were to do the same to me, use a few bits and pieces of my work, I would WANT to deal with it privately and get to the bottom of it before creating even more conflict. If Romito is not cooperative, then you go public and let the rest of the community deal with him, if it's worth that much to you. It happens man, I know you worked hard on VisualV and I know you're probably pissed that you think he "stole" your files, or tweaked them, or copied them, whatever the hell you think it is he did, I understand. It's happened to me, not on GTA V - but with other situations.
In short; take time to look at the facts before spewing bullsh*t on people. If it's true he took your files without your express permission, congratulations - but if it turns out that he took the time to tweak to those, coincidentally similar, settings - then you'll look like a complete jackass.
Don't be so quick to judge people, we do it all the time and it's easy to do, however, some things are best remain unsaid to the public. There are other ways you could have "exposed" Romito, instead of making blatant accusations you could have taken the analytical approach. Updating your fans as to what it is you found, explain what you're doing to correct it and how you want us to react. That would have shown a lot more maturity and respect for other content creators and would have also shown that you are taking the time to discuss the matter with Romito privately before making everything public.
Just some thoughts.
