Theft? Piracy? Heist? Hackers? Violating property rights?

No. No. No. No. No.

Since the code is open source and anyone running Alice’s code is doing so under their own free will, I don’t see how anyone could claim any sort of violation. In fact, claiming that Alice is committing some criminal or unethical act is the only problem I see here.

If others don’t like Alice’s code, then they don’t have to run it. This is a pretty black and white scenario. Free will and free association trump empty rhetoric and emotional attachment.
