Most all of these companies have at one point or another coopted a project, sucked its life blood dry for their own means, and abandoned it. It's a weird, toxic relationship that we accept as normal because some projects can't do without corporate engineer time and money.
FOSS is kind of a different ballgame though. When I think of FOSS I think of my AppStore on PopOS; the apps there are sophisticated and useable, but if I'm being honest they're rarely "the best" at what they do. There's never been a FOSS CAD software that rivals proprietary alternatives, the email clients are lackluster at best, even IRC tends to take a back seat. That isn't to say the apps are bad, they're just not going to be "the best" usually.
Ideally we'd have a single license that encourages corporate use, adoption, and contribution but doesn't encourage them to coopt a project by injecting their engineers and interests into the management of said projects. Ideally there'd be a way for corporate interests to make money reselling software while also paying back, in proportion, to the project. That all seems like a very complicated balancing act.
To be fair, "lackluster at best" describes every email client ever made, proprietary or otherwise (though proprietary ones are better at hiding this under a shiny veneer).
Meanwhile, Kubernetes is probably a bad example, because nobody but large companies need Kubernetes, in the same way that we do not lament that people cannot build a nuclear-powered aircraft carrier in their garage.
There are several examples of OSS being best in class, it's just not the best in every class (yet, at least).
