I don’t personally hate on Apple’s 30%. I hate on Apple’s predatory licensing practices which demand an upfront expenditure before the first unit sells at all.

This. I was so pissed when I saw the EULA for KSP2. I love KSP more than probably any game that has ever been released, due in no small part to the vibrant modding community. The fact that they decided to abuse the very people who made KSP great is disgusting and short slighted.
