I’m not a lawyer, but I’m also not entirely unfamiliar with this sort of thing. In particular, I remember Georgia v. Public.Resource.Org and thus do not accept at face value the notion that the data in question being “summaries and explanations of cases” necessarily means Westlaw is in the right. Even if the Westlaw materials aren’t “officially” incorporated into the law itself the way Georgia did, that doesn’t mean Westlaw should necessarily be entitled to monopolize them, especially if the judicial system is heavily leaning upon them to inform its decisions.
If we’re talking about “most people… switching” then IMO the real biggest factor is when their distro will decide to use it by default.
