Hmm, how do I explain better... the co-pilot is just a tool, just like you can abuse cut&paste to copy code out of any project regardless of the license, so can this copilot.

In the end it still matters what you as the programmer do, and when you make the copilot just paste large parts of code that you don't understand and don't know where it originally comes from (like most of the code found on stackoverflow) then it is probably better not to release that code publicly where anyone can compare it to copyrighted works.

Because even if you you didn't know you were making an copyright infringement (because the copilot helped you do it), it still is a copyright infringement never the less.
