Given who has more money for lawyers, I worry that copyright reform will take the form of small creators being given weaker protection than large entities - for example by making formally registering a copyright on a work necessary to get "full" protections, while self-applied licenses are treated as merely suggestions.

There have been plenty of discussions of this subject here.

Effectively you can't even use the code since it has trampled on licenses which are incompatible with each other. But it is more of a problem for Copilot.
