Because if it's feasible for any company with a war chest to start a court case about a competitor maybe having a matching line of code to theirs via an LLM, then basically every single company with a warchest would be at war with eachother, because they're all using LLMs.

Business and code production would grind to a halt whilst basically every big tech company shares it's entire codebase with every other tech company for discovery. It's basically MAD.

And if it was feasible, given we've had a couple of years of all the big tech companies heavily using LLMs, there should be some notable court cases by now, surely?
