people taking short segments of code that are implementations of common algorithms and claiming those as "copied" by copilot are wrong. it didn't copy, it learned and wrote.
there's multiple examples of it outputting non-trivial code that is identical up to and including comment strings
If microsoft wants a code AI they're free to create their own training data set instead laundering copyright violation of anything that's touched github. It being "hard" isn't an excuse.
Examples of "copied code" provided are pathetic. It's like acquisition of stealing `i` variable from `for` cycle.
