The judge also noted that the cited study itself mentions that GitHub Copilot “rarely emits memorised code in benign situations.”
"Rarely" is not zero. This looks like it's opening a loophole to copying open source code with strong copyleft licenses like the GPL:
- Find OSS code you want to copy
- Set up conditions for Copilot to reproduce code
- Copy code into your commercial product
- When sued, just claim Copilot generated the code
Depending on how good your lawyers are, 2 is optional. And bingo! All the OSS code you want without those pesky restrictive licenses.
In fact, I wonder if there's a way to automate step 2. Some way to analyze an OSS GitHub repo to generate inputs for Copilot that will then regurgitate that same repo.
