Most of the comments I see are taking issue with exact replication of code - this is obviously copyright infringement. The same thing can occur with Stable Diffusion - if I output an image of Iron Man, this is also copyright infringement. Both are bad. Realizing this does not mean that you must inherently be against Co-Pilot or Stable Diffusion. It would be just as bad if I copied the code with a ctrl+c ctrl+v, or drew Iron Man with a pen and pencil.

There are of course some people in there against the very idea of Co-Pilot, but from my quick skimming they do appear to be the minority.

It's almost as if different people have differing opinions.
