Computers don’t violate licenses, people do. If you’re writing MIT code and copilot tells you to include Quake’s square root algorithm and you do so, that’s on you. If Google tells you to include Quake’s square root algorithm and you do so, it’s on you. If stack overflow tells you to do so and you do, that’s on you. In all of those cases it doesn’t matter whether the platform’s software is open source, why should it for copilot?

It’s the poorest of craftsmen who blames their tools. Rise above.

Also, note that simply accessing an online service does not constitute a distribution of software, and thus does not fall under GPL's domain. And "derivative" appears nowhere in the GPL.
