I'd personally not work on SW that could be used by someone else commercially at zero expense. In that sense I never understood why people moved away from GPL and started using "do whatever you want"-license types.
Funny trivia. I spent considerable time working on corporate SW that acted as a gatekeeper for GPL-like licenses. It seems that one of the worst things a corporation can do to itself is use free SW with such a license. Nope. And why should they? There are so many options with so-called "friendly" licenses. Friendly to the corporation that is.
I see it as another aspect of huge corps evading any kind of taxes and IT-crowd actually being OK with it. I mean an unknown dev would be more than proud to do free work for K8S (and many do) just for the sake of putting it in her CV and _maybe_ cash out on it with a better paying role later on. But the fact remains. She, essentially, worked for free for Google, Amazon, Red Hat, etc. All the same as she is OK(ish) with them tax evading because if you get to work for them you'll be extra rewarded (unless you disagree that much of the huge salaries in IT are down to tax evasion).
In any case if you approach FOSS romantically I think you're in for a big let down. It's some form of business transaction. Nebulous and tricky but business nontheless.
