"FOSS licensing" is not what it's about. most software developed commercially in the world is written for a single customer, that gets source code and full rights, so it's freedom-respecting software. a lot of other software is developed for internal use, thus also freedom-respecting software. neither undergo licensing.
even when it comes to licensed software, every one of the top 500 supercomputers runs GNU/Linux; all of big techs relies on and develops free software for their own operations; nearly all of the largest non-IT companies use and prefer free software. all of them realize and pursue the benefits afforded by software freedom.
nonfree software is mostly relegated to suckers and losers, such as small businesses and individual computer users, who are trained and driven into dependence on nonfree software for benefit of software providers, surveillance capitalism and whatnot. let's not be ridiculous by suggesting that people prefer to be spied on, imposed misfeatures, denied desirable features, and forced into monopolies.
