For personal use, it is ok, not because it is right, but because practically it is almost impossible to track thousands of individuals
altering your code to fit their personal feeling, for at-home use only.
But if one intends to sell it in the market, then should ask himself the question: Will that hurt or affect the sales of the original work?
if yes and the sales volume is affected, then it is wrong to clone it. Unless, as mention, you come up with new original and major
enhancements that's useful to users and they can't find it in the original work... changing some pictures or the title or colors are not
considered substantial and major enhancements.
