Sure - though that’s all generated by the coding agents. So it shouldn’t be uploading original hand-written code (unless the coding agent is running on a legacy codebase).
Obviously it’s not something everyone is going to be comfortable sharing, but YC is transparent about what is shared and how it’s used.
Edit:
I now see you have to explicitly run it in every directory you want shared - i.e., it doesn’t t scan your whole disk looking for stuff to upload. So there’s every opportunity to limit what it uploads to only what you want to share.
