If that is so, people will stop writing open source. Then this model will use its own output until it produces bland garbage like a camera filming its own output stream.
Linux has a lot of corporations contributing code to it. Tensorflow is backed by Google. Plenty of other projects are released as open source by companies, not people. I don't see companies crying about Copilot, so their employees will keep writing open source when instructed as such by their managers.
I write open source code to benefit others and to put more learning material in to the world. If I was so paranoid about other people using it I would have made it proprietary.
