IIpe, labels are something other people use to compartmentalize things they don't like or understand. If someone calls blacking out the parts on an off-road vehicle "murdered-out" then they don't understand the purpose of using the color black.
But black as become the new bling in many ways. A lot of people black out stuff just for the look, not for practical reasons.
Blacking stuff out simply because it looks good is no different than someone adding chrome to a vehicle. Someone who takes their badges off and paints them black is as much concerned about looks as someone with a chrome grille. Not that there is anything wrong with either, but we shouldn't just assume that black means someone is a hardcore wheeler, and chrome means they spend all their time at the mall.
The manufacturers know the there is a black trend too, rims are now even available in black chrome.
Back to the original question, the last chrome rims I had were bought because they were the cheapest rim I could find in the size I wanted. After scratching them up, I rattle canned them black. Of course I could have just left them, but they were oxidizing and looked like crap.
Black paint is generally easy to touch up, and when it comes time to wash the vehicle you don't have to spend long cleaning them.
Generally speaking black is more practical than chrome, and usually requires a lot less maintenance.
