Apple's primary value driver (when it mattered) was luxury margins on mediocre tech. Without rampant demand, you don't have market stratification. If substantial regulation like the DSA existed in 2014, Apple's business model would look radically different today.

Because Apple under Steve Jobs worked because Steve had full control. Zero chance they become successful run by committee or group ownership or whatever. And they also needed venture capital in the beginning afaik.

I don't think Apple could have existed as it did under Jobs in any other system.
