Just a heads-up that the person who writes this is Tim Davis[0], author of the legendary CHOLMOD solver[1], which hundreds of thousands of people use daily when they solve sparse symmetric linear systems in common numerical environments.

Even if CHOLMOD is easily the best sparse symmetric solver, it is notoriously not used by scipy.linalg.solve, though, because numpy/scipy developers are anti-copyleft fundamentalists and have chosen not to use this excellent code for merely ideological reasons... but this will not last: thanks to the copilot "filtering" described here, we can now recover a version of CHOLMOD unencumbered by the license that the author originaly distributed it under! O brave new world, that has such people in it!

In case anyone interprets this literally: if copilot regurgitates literal code it was trained on that doesn't actually give you an unencumbered version.

So how long till new software licenses that prohibit any use of code for model training purposes? I'd be willing to bet there's a significant group of people that won't be happy either its literal or not, the fact that it was used in the training might be enough.
