I've been finding co-pilot really useful but I'll be pausing it for now, and I'm glad I have only been using it on personal projects and not anything for work. This crosses the line in my head from legal ambiguity to legal "yeah that's gonna have to stop".
do you have the "don't reproduce code verbatim" preference set?
I grant that if most people are using it one way here I was likely wrong for the way it is typically used by the normal open source community, I followed up with a reply saying it would likely be more correct for me to have said "improperly licensed" to be included in the training set.
Still it being private means it probably shouldn't be in the training set anyway regardless of license, because in the future, truly proprietary code could be included, or code without any license which reserves all right to the creator.
