This is unclear. I have never seen an open source license that was explicit about this. Seems like a grey area.

It's not even clear how often training machine learning algorithms on code results in copyright violations. CoPilot does have a setting to detect and disallow direct copying, but how well does it work?

This legal uncertainty is enough that I wouldn't advise using it, but maybe people who use it will be fine?

It's messy enough it's likely to end up a Supreme Court case in US (and I wouldn't want to be a party to it).

Europeans will probably preempt that with legislation.
