How do you explain open source software then? Why is Linux still being developed?
Epic Games earn billions with their Unreal Engine and Fortnite and they aren't afraid of pirates.
Unreal engine is not technically open source, I’m aware that their revenue from it is that significant compared to Fortnite and they make money by taking a share of revenue from it’s users.
Not sure how all of that is relevant for open source though . IBM/Red Hat, Google or even Oracle would be much better examples
