Ask yourself why you feel that way, though. If I pixel-by-pixel copy discrete ideas from 20 different sites to build my own, that seems different, legit. Zero new code by me, I just stitched it together.
As we reduce 20, somehow that legitimacy erodes and at 1 it's "disrespectful". Where along that line was it wrong?
The "problem" we perceive is not stealing, it's stealing from only 1 place.
