The benefit of not having lawyers is pretty limited. There are larger forces at work that mean the larger an organization grows the more it will be concerned with licenses. The idea that ignoring licenses will allow a company to outcompete one that doesn’t is wishful thinking at best. Moreover, I’m not making a judgment on these practices, I’m just stating a fact.

The lawyers don't even have to do anything. I avoid any code that's not MIT or equivalent for work-related things because I don't want to run the risk of polluting company code. The only exception is elisp, because that only runs in Emacs.
