Odd analogy to use with Microsoft Windows, since GPT-3’s source is available, along with a series of papers that enables anyone with the money and knowledge to implement it themselves.
The reasons why MS windows and GPT-3 cannot easily be modified by anyone are different, but the result is the same: you're stuck with what you're sold.
To clarify: MS windows is closed source, but you can't very well train a large GPT model unless you're someone with the resources of OpenAI. So you're stuck with whatever they choose to train and make available to you.
