IIRC they just block that suggestion if they detect it's a copy now
More specifically it's an option, the VSCode Copilot extension asks you to configure it and takes you to a GitHub page where you can choose what happens if a suggestion is a direct copy.
What they're doing does feel icky, and they could have mitigated a few concerns by a) making the inventory of the full training set public and b) at least attempt to attribute if there is a direct copy (which by their own admission happens about 0.1% of the time). These seem very simple steps they could take, and takes away the "shady behavior" argument.
