I will try to stay polite because if I say what I really think of this comment I will be banned for life of this website. And that applies to all the others who think they are so smart because they don't follow the trend: "I'm so special and have a so powerful mind because I don't let evil companies put useless lights in my computer".
If you don't like it, don't buy it. There's always an option without RGB. Pick those. But trying to shame people who like something you don't is really dumb and despicable. If I don't like strong cheese, I could do like you and say I don't understand why so many people like strong cheese and it shouldn't even exist because, you know, I personally don't like it. Why do companies try to dictate the food offer with their disgusting cheese? But that would be insanely dumb, isn't it?
I like to make my setup looking appealing when I look at it. It brings me joy and doesn't harm you in any ways. And if you suffer from a so bad focus problem that a few color lights distract you from your games then yeah, stay away from RGB and stick with your sad setup.
