"Over the years it has been clear that we in the “open source” camp (as opposed to the “free software” camp) were wrong all along. We won the debate, and gained little for users or developers. All that our efforts did was to make it easier for big corporations build things more cheaply and for billionaires to become trillionaires."
Did anyone ever claimed, open source was a way to get super rich in money?
It was always about access to source, to study, to tinker, to improve upon. We now have huge ressources of open source software to learn from - indeed a win I say.
And it is not clear at all to me, that the alternative timeline would have been any better, if FOSS and a strong copyleft would have won as developers choice and standard - I rather would expect it to be way more niche - and trillionaires would be as rich as ever.
