Apple began as people making home computers in their garages, so they could have computers. How on earth can you, on Hacker News, not understand the compelling allure of having a computer in your home in an era where that was just about unthinkable?
There's a lot of homo economicus in this Hacker News comments section. It's genuinely weird and unsettling, though I guess it stands to reason that here's where you'd see 'em. We're talking human paperclip maximizers, just generalized to 'profit'. Open source and free software are kind of kryptonite to this mindset, an active danger, therefore you're seeing a lot of pushback.
Wealth is for DOING STUFF.
Open Source maximizes DOING STUFF, not 'profit'. It can actually reduce the amount of profit in the world, through decentralizing power and undermining the ability to engage in profit-taking and the cornering of markets.
It is frequently engaged in by people who have reasonable amounts of wealth in their own right and have turned their attention to doing stuff rather than amassing more wealth the most efficient way they can. Sometimes, open source amounts to doing stuff in the most efficient way you can, directly competing with anybody who's stuck having to also make profit while doing stuff.
This is just reality.
