Ok. So instead of whining about it on Twitter sue GitHub. No matter what you think of Copilot, establishing some case law on AI-generated code will be beneficial to everyone.
It goes beyond code. Also photos, art, text, etc. Be careful what you wish for. Whether you like it or not, with a stroke of a pen Congress or the Supreme Court in the US could probably wipe out the legal use of a huge amount of the training data used for ML.
Accessing a computer system without permission is illegal. Search engines operate under the assumption that they have permission to access any public available server unless explicitly forbidden.
If a company or person assume they got copyright permission to any work public accessible then they will quickly find out that such assumption is wrong, and that they require explicit permission.

And why should opt-out be a reasonable norm? To be clear, the internet (among many other things) breaks down if every exchange of information is opt-in. Sharing of photographs taken in public places is another example. But the internet basically functions because people share information on an opt-out basis (that may or may not even be respected).
