Anyone can already generate proprietary code that is identical to your GitHub project's code just using copy and paste.

For people that care to respect copyright, there's a copilot setting to block exact copies of code in the training set (which only happens a tiny percentage of the time, unless you're actually trying to make it happen).

For people that don't care to respect copyright, git clone is a way more efficient way to violate your license.
