> 1. You most likely agreed to that by using GitHub.
Are you saying that I would need all the original authors consent to upload a repo to github even if I include all the original attribution and licenses? Because what you are implying is that when uploading I'm granting github a license far outside the bounds of the license included, which only all the contributors can do. For example, would the linux project need to contact each and every contributor ever to upload a mirror to github, since their contributions were under GPL but you are implying that the license given to github is much, much broader?
This would make any project not originally started on github and with a few contributors basically impossible to host there.
> 2. Copy&Pasting Code by manual search exists.
The question is who is doing the infringement here. Github copilot is obfuscating the copying and telling it's users that the code is theirs to use, own, etc. as they please but is also taking large chunks of code it does not have the right to redistribute, even less grant licenses to.
